There are several forms of female orgasm singled out by sexologists nowadays. Based on the localization of an orgasm there are four physiological forms - clitoral, vaginal, uterine (the orgasm of the cervix), and perineal, as well as several pathological ones - oral, rectal (or anal), and nipple ones.

An orgasm is a complex psycho-physiological process, which is based on the corresponding processes in the brain. The stimulation of the brain's specific zones of pleasure leads to an objective display of an orgasm. These zones are turned on under the influence of the impulses going through the female reproductive organs. The female's body motor activity resembles seizures. In some cases the body tenses up and stretches out, the pelvis lifts up and the whole body arches supported by the back of the head and the heels, the hands tense up and stretch out, jaws clench, eyes are tightly shut. In other cases the body arches, wiggles, makes heaving motions, hands and legs make sharp chaotic movements, the head spins in all directions. All of this is accompanied with sounds effects (cries, screams, sobs, wails, squeaking of the teeth, as well as the sounds muted by the willpower or by the spasm of the speech muscles, moans, sighs, and so on). Sometimes separate words and incoherent phrases escape the mouth. A spasm takes place, which is quite an abrupt contraction of the muscles of vagina, uterus, perineum and other muscles of the small pelvis. Usually a young girl that has not given birth and has a well-developed muscular system has 2-3 strong spasms and several weak ones, which gradually die out. Women who have a weaker muscular system, are older, and have given birth have only one strong spasm and 1-2 weak ones. All of these spasms can be felt with the man's penis. The increase of the discharge in the vagina sometimes is so drastic that the penis loses the feeling of the vaginal walls. In rare cases a large amount of fluid even overflows outside. During the orgasm the nipples increase in volume and harden (the nipple erection).

So how important is it for male and female sexual organs to be of matching size in order for a woman to be able to reach an orgasm? There has always been a significant importance given to the size of reproductive organs in sexology and in society. In reality things are way simpler. First of all, a successful sexual life does not require a penis of particularly large size. It is well known that a woman can experience four types of orgasms, three out of which (clitoral, vaginal, and perineal) do not depend at all on the size of male genitals. The fourth type of orgasm - the uterine one - requires the penis to be a certain length, but a quite moderate one, since the majority of women have their cervix situated relatively not deep. There are no correlations that exist between the overall size of the man's body, namely the size of a man's penis, and the size of a woman's vagina. The anatomical non-conformity can take place only when there is an obvious vaginal pathology (its underdevelopment, scarry stricture due to previous injuries, burns, and so on). In all other cases the male and female sexual organs present a functional system, in which the vagina can stretch a great deal if a man's penis is large, and on the contrary, it can contract and tightly envelop a small penis.

So what is a clitoral orgasm? There used to be a wide-spread opinion that this type of orgasm is characteristic for very young women, and as women get older the orgasm relocates to the vagina. However, it is not so. The clitoral orgasm can be characteristic for any woman regardless of her age, constitution, and so on.

In order to reach a clitoral orgasm the clitoral stimulation is necessary. Women, whose most common orgasm is a clitoral one, can almost never reach it if having sex in the most common missionary position. The clitoris remains outside of the area of stimulation. When having a sexual intercourse in the missionary position, the necessary stimulation of the clitoris is achieved by its contact with the dorsum of the penis, for which the penis should be inserted under an angle (top-down). It is possible if the distance between the clitoris and the vagina's entrance is normal (about 1 inch). If the clitoris is located higher, the penis will not reach it. In this case it is necessary to either change the position or to apply small monotonous stimulating movements to the clitoris with your finger during foreplay and the sexual intercourse itself. The clitoris' head is rich in blood vessels and nerve endings, therefore stimulating it with your hand should be very light and tender. Sometimes it is useful to use vaseline or to moisture your finger by inserting it into the vagina. If the clitoris' head is too sensitive the finger stimulation can be transferred higher. These parts of the clitoris are hidden deeper and so the stimulation can be stronger. Women with the clitoral type of orgasm will not enjoy having sex from behind. The following position is way more acceptable: start having sex in the classical missionary position and then push the woman's legs together, so that the penis was stimulating the clitoris with every friction. You can switch places - a man on the bottom, and a woman on top. The signs of the clitoral orgasm are a considerable increase of the clitoris' size (an erection), and its temperature rising.

The second type of female orgasm is a vaginal one, or commonly known as the g-spot orgasm. The erogenous area in this case is the lower third of the front wall of the vagina, which requires a special technique consisting of the tight pressing of a penis to the front wall of the vagina during frictions. You can also practice small frictions that are not deep and affect only the lower part of the vagina, which would intensify the impact on the lower third of the front wall of the vagina. There are also cases of the combination orgasm or the clitoral-vaginal orgasm. To achieve it, try to simultaneously stimulate both the clitoris and the front wall of the vagina during foreplay, and to simultaneously stimulate both erogenous zones with your penis or hand during the intercourse.

To achieve any type of orgasm, it is necessary for the cavernous bodies of the clitoris to be filled with blood to the maximum, and the lower part of the vagina is covered with the muscles tightly connected to the cavernous bodies. When contracting these muscles, a woman not only intensifies the filling of her own cavernous bodies by contracting the base of the penis during the intercourse but also complicates the blood's outflow from the cavernous bodies thus intensifying the partner's erection and creating additional pleasurable sensations.

Unfortunately, these important muscles do not always work to their full potential. Some women have them low-power, and some women do not properly use them. The sexologist's task is to teach a woman to use these muscles in both cases. The power of any cross-striated muscle increases with exercising therefore women should do a special sex work-out: flex the main vaginal muscle-constrictor over and over again on a daily basis.

The lower third of the vagina and perineal muscles play a very important role in the body. They form an orgasmic sleeve, the contractions of which (5-12 contractions with 0.8 seconds interval) create the vaginal orgasm. After an orgasm the vaginal sleeve and the walls quickly relax. With the vaginal form of orgasm a woman can experience pleasure in any position.

During the uterine orgasm the contractions of the uterus start from its bottom and transfer to the whole body. The strength of the uterine contractions equals to the strength of the orgasm. This orgasm is known for the so-called "suction effect", when the cervix "sticks" to the upper part of the vagina, after which the uterus goes back to the original position.

This type of orgasm requires the stimulation of the cervix. If a penis is not very long or if the vagina is too big, a penis may not reach the cervix. In this case, a woman should lie on her back and pull her legs to the stomach, which shortens the vagina considerably. Another option is for a man to lie on his back and for a woman to squat down on top of him. Sometimes the cervix is situated not in the posterior fornix of the uterus, but instead is facing forward. In order to put the uterus back into its place, you should change the position, so that a woman is lying down on her stomach or on her side. In this position the penis goes not in the posterior fornix, but in the front one. If a woman is obese, the coitus is only possible in the position when a woman is on her side with her legs strongly bent in her hip joints or in a classic Bozeman’s position when a woman is on her knees leaning on her forearms and a man is standing on his knees behind her, commonly known as doggy style. This same position is almost the only possible position to have sex if a man is obese.

The technique of the sexual intercourse to achieve this type of orgasm consists in a man carrying out deep frictions thus rhythmically stimulating the cervix and the posterior fornix of the uterus. Although you should avoid hitting the cervix too hard.

The fourth type of orgasm and a very rare one is the perineal orgasm. The nerve impulses start in the perineum when it comes into the state of vibration. Women with this type of orgasm sometimes experience it while riding a horse, a bicycle or a motorcycle. The technique of the sexual intercourse consists in stimulating the lower part of the vaginal back wall with the head of the penis.

So what happens to a woman after the sexual intercourse? The woman's sexual arousal goes down gradually, and because of this women are sensitive to the men’s sexual indifference after the intercourse is over. There are a lot of complaints about men switching to routine conversations right away or even falling asleep. These complaints express the women's need in the post-coition caresses. These caresses should not be of sexual nature and thus should not be about stimulating the erogenous zones, but on the contrary consist of the stimulating the non-erogenous zones of a woman's body. The psychological content of these caresses is the display of gratefulness, tenderness, emotional relaxedness. At the same time during the post-coition caresses a woman is displaying her gratefulness to a man and her appraisal of him as a sexual partner. Every man during and after the sexual intercourse has a hidden need to receive the assessment of his actions from a woman. It contributes to his self-affirmation but at the same time a man becomes especially vulnerable to any kind of reproaches. This is why it is important that a woman expresses any concerns she might have about the foreplay and the intercourse itself at any time but not immediately after sex. At this time a woman’s assessment should be positive no matter what. Keep in mind that this is not only the concluding assessment of that night's intimacy, but also the stimulus for the future. A man will always want to live up to the woman’s assessment especially if it was slightly above the objective evaluation. Of course sometimes life takes over and a husband or a wife still have to get up after just being intimate and go take care of the everyday stuff, but psychologically the best state of being after sex is sleep. A woman should always fall asleep before a man, resting in his embrace, and not the other way around.
