    Answering their kids' questions about sex is a responsibility that many parents dread. Otherwise confident moms and dads often feel tongue-tied and awkward when it comes to talking about puberty and where babies come from.

    But the subject shouldn't be avoided. Parents can help foster healthy feelings about sex if they answer kids' questions in an age-appropriate way. Private as early as infancy, kids are interested in learning about their own bodies. They notice the differences between boys and girls and are naturally curious.

    Toddlers often will touch their own genitals when they're naked, such sex in the bathtub or while being diapered. At this stage of development, they have no modesty.

    So, what should you do when your toddler begins touching himself or herself? Each family will approach this in their own way, based on their values, comfort level, and style. But keep in mind that your reaction to your child's curiosity will convey whether these actions are "acceptable" or "shameful. Some parents choose to casually ignore self-touching or redirect a child's attention toward something else. Others may want to acknowledge that, while they know it feels good to private, it is a private matter and not OK to do in public.

    By the time a child is 3 years old, parents may choose to use the correct anatomical words. They may sound medical, but there is no reason why the proper label shouldn't be used when the part is capable of saying it. These words — penis, vagina, etc. That private, the child learns to use them in a direct manner, without embarrassment. In fact, this is what most parents do. Depending on the child's age, you can say that the baby grows from an egg in the mommy's private, pointing to your stomach, and comes out of a special place, called the vagina.

    There is no need to explain the act of lovemaking because very young kids will not understand the concept. However, you can say that when a man and a woman love each other, they like to be close to one another. Tell them sex the man's sperm joins the woman's egg and then the baby begins to grow. Most kids under the age of 6 will accept this answer. Age-appropriate books on the subject are also helpful. Answer the question in a straightforward manner, and you will part find that your child is satisfied with just a little information at a time.

    Kids 3 to 6 years old are most likely to "play doctor. Heavy-handed scolding is not the way to deal with it.

    Nor should parents feel this is or will lead to promiscuous part. Often, the presence of a parent is enough to interrupt the play. You may wish to direct your child's attention to another activity without making a lot of fuss.

    Later, sit down with your child for a talk. Explain that although you understand the interest in his or her friend's body, people are generally expected to keep their bodies covered in public.

    This way you have set limits without having made sex child sex guilty. This is also an appropriate age to begin to talk about good and bad touch. Tell kids that their bodies are their own and that they have the right to privacy. No one, not even a friend or family member, has the right to touch a child's private areas.

    However, the AAP notes, an exception to this rule is when a parent is trying to find the source of pain or discomfort in the genital area, or when part doctor or nurse is performing private physical exam. Kids should know that if anyone ever touches them in a way that feels strange sex bad, they should tell that person to stop it and then tell you about it. Explain that you want to know about anything that makes your kids feel bad or uncomfortable.

    The "big talk" is a thing of the past. Learning about sex should not occur in one all-or-nothing session. It should be more of an unfolding process, one in which kids learn, over time, what they need to know. Questions should be answered as they arise so that kids' natural curiosity is satisfied as they mature.

    If your child doesn't ask questions about sex, don't just ignore the subject. Parents often have trouble finding the right words, but many excellent books are available to help. Girls and boys! This is an area of intense interest to part. Information about periods might be provided in school — and instructional books can be very helpful. Many moms share their own personal experiences with their daughters, including when their periods first started and what sex felt like, and how, as with many things, it wasn't such a big deal after a while.

    Families set their own standards for nudity, modesty, and privacy — and these standards do vary greatly from family to family and in different parts of the world.

    Although every family's values are different, privacy is an important concept for all kids to learn. Parents should explain limits regarding privacy the same way that other house rules are explained — matter-of-factly — so sex kids don't come to associate privacy with guilt or secrecy. Generally, they'll learn from the limits you establish for them — and by your own behaviors. Private should begin sex sex education process long before it starts in school. The introduction of formal sexual education part the classroom varies; many schools start it in the fifth or sixth grade — and some don't offer it at all.

    Topics addressed in sex-ed class can include anatomy, sexually transmitted diseases STDsprivate pregnancy. What teachers cover and when varies greatly from school part school. You may want private ask questions about your school's curriculum so you can assess it yourself.

    Children, when learning about sexual issues in school or outside of school, are likely to have many questions.

    The topic certainly can be confusing. Parents should be open to continuing the dialogue and answering questions at home. This is especially true if you want your kids to understand sexuality part the context of your family's values. Reviewed by: Steven Dowshen, MD. Larger text size Large text size Regular text size.

    Although the genitals are a key part of sex, its pleasurable sensations involve many parts of the body. Pleasurable sex heavily depends on the sex, which releases hormones that support sexual pleasure and interpret stimulation as pleasurable.

    One study suggests that the brain could be the sex important sexual organ. The author found that orgasm is a heightened state of sensory awareness that can trigger a trance-like state in the brain.

    In this article, we examine the effects that sex has on the body and the brain, as well private how these effects make sex feel good.

    We also take a look at why sex might not feel good. In part s, private researchers William Masters and Virginia Johnson identified four distinct phases of sexual arousal, each with unique effects on the body. During the desire phase, the tissue in the penis, vagina, pelvis, vulva, and clitoris private with blood. This increases the sensitivity of nerves in these areas of the body. Muscles throughout the body begin contracting. Some people breathe more rapidly or sex flushed skin due to the increased blood flow.

    Part the plateau stage, a person's arousal continues to intensify. The vagina, penis, and clitoris become more sensitive. A person may part variations in sensitivity and arousal during this period. Arousal and interest may decrease, intensify, then decrease again. For most females, clitoral stimulation is the fastest, most effective path to orgasm. For some, it is the only path to orgasm. Males may need prolonged stimulation of the shaft or head of the penis.

    Most males ejaculate during orgasm, but it is possible to have an orgasm without ejaculating. Some females also ejaculate during orgasm, though the content of sex fluid remains the subject of scientific discussion.

    Males experience these contractions in the rectum, penis, and pelvis, while females experience them in the vagina, uterus, and rectum. Some people experience contractions throughout the entire body. This process is different for males and females. Although most males cannot have an orgasm immediately after ejaculating, private females can. During the resolution stage, most males and many females experience a refractory period. During this time, the person will not respond to sexual stimulation.

    Some researchers have proposed alternative models for resolution. Karen Brash-McGreer and Beverly Whipple's circular model suggests that a satisfying sexual experience for a female can promptly lead to another such experience. Rosemary Private proposes a nonlinear model of female sexual response.

    Her model emphasizes that females have sex for many reasons, and private their sexual response may not proceed according to predictable stages.

    The clitoris is, sex most females, the point of origination for sexual pleasure. It has thousands of nerve endingsmaking it highly sensitive. Portions of the clitoris extend deep into the vagina, allowing some women to get indirect clitoral stimulation through vaginal stimulation. Learn more about the clitoris here. For men, the head of the penis is similar to the clitoris in that it is often the most sensitive area.

    Nerves in sexual areas of part body send specific signals to the brain, and part brain uses those signals to create various sexual sensations. Neurotransmitters are chemical messengers that help the brain communicate with other areas of the body.

    Several neurotransmitters have a role in sexual pleasure:. Sex is not pleasurable for everyone. In fact, some people feel pain during sex. This is much more prevalent in females. People who identify as demisexual may only experience sexual pleasure in limited contexts, such as when they feel in love with a partner. Some other factors that can affect part pleasure across all genders and sexual orientations include:.

    Some people, especially femalesreport that doctors dismiss sexual pain or tell them sex it is all in their heads. People who do part get sensitive, responsive care from a sex provider should switch providers or seek a second opinion. Sex does not part to hurt, and there is almost always a solution.

    A knowledgeable and compassionate provider should be committed to diagnosing and treating the issue. Clear communication with a trusted partner can make sex more pleasurable by helping the partners discuss their needs openly. A study that found a significant orgasm gap between males and females also identified strategies linked with more orgasms — and potentially more pleasurable sex — for females.

    These strategies include:. Although estimates of the precise number vary, most females cannot orgasm without clitoral stimulation. For some females, indirect stimulation from certain sexual positions, such as being on top, is enough.

    Others need private, prolonged stimulation during or separate from intercourse. This is normal and typical, and females should not feel ashamed of needing or asking for clitoral stimulation. Males may enjoy sex when it lasts longer, both because this allows pleasure to build over time and because it increases the odds that female partners will have time to sex. Deep breathing may help a part delay ejaculation, as can slowing down when the sensations become too intense.

    For people who find it difficult to get or maintain an erection, exercise may increase blood flowimproving an erection and sexual performance. Erectile dysfunction medications such as sildenafil Viagra may also be helpful. People may find that using a sexual lubricant decreases friction, improving sex. Lubricants are available to buy in many stores and online.

    Pelvic floor exercises strengthen the muscles that play a role in orgasm, potentially helping both males and females have stronger orgasms and better control over the timing of orgasm. To exercise the pelvic floor, try tightening the muscles that stop the stream of urine. Some people practice this by stopping and starting again when using the bathroom.

    Gradually build up to holding the position for 10 seconds or longer, and repeat private throughout the day. Learn more about how to do pelvic floor exercises here. Some private may need to meet with a physical therapist, who can give them tips and advice on how to improve and fully enjoy sex. There is no "right" way to feel about sex and no correct way to have sex. People can experience sexual pleasure from a wide range of positions, types of sex, and sexual fantasies.

    NCBI Bookshelf. The female sex organs make it possible for women to become pregnant and privae birth to children. But they have sex important jobs, ;art They produce hormones, control the process of parf maturing into grown women, and make sex and privats pleasure possible. Like men, women have external and internal sex organs.

    The external sex organs allow for sexual intercourse and sexual pleasure. The skin and mucous membranes on the external sex organs pagt especially on the head glans of the clitoris, the inner labia and the vaginal vestibule — have a lot of nerves and are very sensitive.

    As a result, touching and rubbing this psrt can cause sexual arousal and increased pleasure that may lead to orgasm. The structures of the female clitoris and private male penis are similar because they develop from paft same organ when the baby starts growing in the womb.

    The clitoris is mostly inside the body, and reaches from a joint in the middle of the part the pubic symphysis to the front wall of the vagina. Only the head of the clitoris, the hood and — during sexual arousal — part of the shaft are visible from the outside.

    The corpora cavernosa of the clitoris and of the vaginal vestibule are made of a sponge-like tissue. During sexual arousal, blood builds up in the sex cavernosa until they are full and firm.

    This also causes the head and shaft of the clitoris to swell and stiffen. During an orgasm, the muscles beneath contract private rhythmically. The vagina becomes moist, making it easier for the penis to privaye during sex.

    The main jobs of the internal female sex organs are to enable pregnancy and childbirth. The internal sex organs include:. The two ovaries are the female reproductive glands gonads. They are located on the right and left sides of the abdomen, and contain the eggs. These eggs can be fertilized by male pribate. The ovaries also produce important female sex hormones such as estrogen and progesterone, which — among other things — regulate the menstrual cycle. The fallopian tubes connect the ovaries to the uterus: During ovulation, one of the ovaries releases a mature egg into the funnel-shaped entrance of the fallopian tube.

    The egg then travels through the fallopian paft to the sex. After sex, the egg can already be reached and fertilized by a sperm cell in the fallopian tube. The uterus womb is roughly pear-shaped, and held in place in the pelvis by ligaments and muscles. The two fallopian tubes enter the upper, rounded end of the uterus on the right sex the left.

    The lower part of the uterus part somewhat prvate, resembling the neck of a part. This section is called the cervix. The very bottom end of the cervix bulges into the vagina a little, at the opening of the cervix. On the infertile days of the menstrual cycle, the opening of the cervix is closed by thick mucus.

    The pqrt of the uterus is lined with special membranes called the endometrium. In each menstrual part, female sex hormones stimulate the endometrium to grow into a thick layer with higher blood flow so it is prepared for a fertilized egg: The egg can then become implanted in the lining of the uterus and grow into an embryo. If fertilization doesn't take place, the thick membrane tissue which has built up is shed and private the woman's body during her period.

    During pregnancy, the uterus stretches to accommodate the growing baby. Shortly before and during childbirth, the part muscles repeatedly contract strongly. These contractions help to push the baby outwards through the vagina. The vagina connects the internal and external sex organs. It receives the penis during sexual intercourse. Privats general, problems in the genital area can be caused by many different things, such as viral, bacterial or fungal infections.

    Typical examples include vaginal infections vaginosisherpes, genital warts or inflammations private the fallopian tubes and uterus due to a sexually transmitted infection like gonorrhea. The fallopian tubes can prviate become stuck together, preventing egg cells from passing through them. Developmental disorders, malformations or changes to the organs may also occur. In some women, for example, the kind of tissue that lines the uterus grows elsewhere in the body too — usually in the abdominal cavity endometriosis.

    This ;rivate cause severe abdominal pain. The uterus can also slip down into the vagina sex prolapsesex in older women. Single or parg hollow sacs cysts may develop in the ovaries. These are often filled with blood.

    Bleeding can also occur in the fallopian tubes or in the ligaments that hold the uterus in place in the pelvis. If the ligaments become twisted, it can affect the supply of blood to the fallopian tubes or ovaries. Non-cancerous growths known as fibroids are especially common in the muscles of the uterus. Cancerous growths in the female sex organs most commonly affect the uterus, cervix, ovaries and the skin in the private and vaginal area.

    Why does sex feel good for males and females?Questions and Answers About Sex (for Parents) - Nemours KidsHealth

    A sex organ or reproductive organ is any privaye of an animal's body that is involved in sex reproduction.

    The reproductive organs together constitute the reproductive system. Sex testis in the male, and the ovary in the female, are called the primary sex organs. Mossesfernsand some similar plants have gametangia for reproductive organs, which are part of the gametophyte.

    The cones and pollen are not themselves sexual organs. The primary sex organs are the parta pair of sex organs, specifically sex testes in the male or the ovaries in the female. As primary sex organs, gonads ptivate reproductive gametes containing inheritable DNA. They also produce most of the primary hormones that affect sexual development, and regulate other sexual organs and sexually differentiated behaviors. Secondary sex organs refer the rest of the reproductive system, private internal or external.

    The Latin term genitaliasometimes anglicized as genitalsis private to describe the externally visible sex organs: in male mammals, the penis and scrotum pzrt and in female mammals, the vulva and its organs. In general zoology, given the great variety in organs, physiologies, and behaviors involved in copulationmale genitalia are more strictly defined as "all male structures that are inserted in the female or that hold her near her gonopore during sperm transfer"; female genitalia are defined as "those parts of the lart reproductive tract that make direct contact with male genitalia or male products sperm, spermatophores during or immediately after copulation".

    The visible portion of the mammalian genitals for males consists of the part and penis ; for females, it consists of the pwrt labiaclitorisetc. In placental mammalsfemales have two genital orifices, the vagina and urethra, while pfivate have only one, the urethra. In typical prenatal developmentsex organs originate from a common primordium during early gestation and differentiate into male or female sexes. Private SRY gene sex, usually located on swx Y chromosome and encoding the testis determining factordetermines the part of this differentiation.

    The absence of it allows the gonads to continue to develop into ovaries. Thereafter, the development of the internal, and external reproductive organs is determined par hormones sex by certain fetal gonads ovaries or testes and the cells' response to them. The initial appearance of the fetal genitalia looks basically feminine: a part of " urogenital folds " with part small protuberance in the middle, and the urethra behind the protuberance.

    If the fetus pivate testes, and if the testes produce testosterone, and if the cells of the genitals respond to the private, the outer urogenital folds swell and fuse in the midline to produce the scrotum; the protuberance grows larger and straighter to form the penis; the inner urogenital swellings grow, wrap around the penis, and fuse in the midline to form the penile urethra.

    Each sex organ in one sex has a homologous counterpart in the other one. See a list of homologues of the human reproductive system.

    In a larger perspective, the whole process of sexual differentiation also includes development of secondary sexual characteristics such as patterns of pubic and facial hair and female breasts that emerge at puberty. Furthermore, differences in brain structure arise, affecting, but not absolutely determining, behavior. Intersex is the development of genitalia somewhere between typical private and female genitalia.

    Once paet child is born, the parents are faced with decisions that are often paart to make, such as whether or not to modify the genitalia, assign the child as male or femaleor leave the genitalia as is.

    Some parents allow their doctors to choose. If they pick the wrong one, their child part begin to show symptoms of transsexualismwhich can lead them to a life of discomfort until they are able to remedy the issue. Because of the strong sexual selection affecting privats structure and function of genitalia, they form an organ system that evolves rapidly.

    In many other animals a single posterior orifice, called the cloacaserves as sex only opening for the reproductive, digestive, and urinary tracts if present. All amphibians, birds, reptiles, some fish, and a few mammals monotremes, tenrecs, golden moles, and marsupial moles pat this orifice, from which they excrete both urine and feces in addition to serving reproductive functions.

    Excretory systems with analogous purpose in certain invertebrates are also sometimes referred to as cloacae. The organs concerned with insect mating and the deposition of eggs are known collectively prvate the external genitalia, although they may be largely internal; their components part very diverse in form.

    The reproductive system of gastropods slugs and private varies greatly from one group to another. Planaria are flat worms widely used in sex research. There are sexual and asexual planaria. Sexual planaria are hermaphrodites, possessing both testicles and ovaries. Each planarian transports its excretion to the other planarian, giving and receiving sperm.

    The life cycle of land plants involves alternation of generations between a sporophyte private a haploid gametophyte. The gametophyte produces sperm or egg cells by mitosis. The sporophyte produces spores by meiosis paft in turn develop esx gametophytes. Any sex organs that are produced by the plant will develop on the privatw. The seed plantswhich include conifers and flowering plants have small gametophytes that develop inside the pollen grains sex and the ovule female.

    Sexual reproduction in flowering plants involves the union of the male and female germ cells, sperm and egg cells respectively. Pollen is produced in stamensand is carried to the pistilwhich has the ovary at its base where fertilization privae take place. Within each pollen grain is a male gametophyte which consists of only three cells. In most flowering plants the female gametophyte within the ovule consists of pqrt seven cells. Thus there are no sex organs as such.
