Physiologically, a person goes through these stages of sexual response cycle that built: sexual desire, sexual arousal, and as a result orgasm and resolution phase.
The regulatory functions of the sexual sphere of man, which nature had created organs, such as the cerebral cortex, because recurrent structures, and some of the centers of the spinal cord. All sex centers that regulate sexual activity, are closely linked, and, of course, is obvious, interaction, only to obey, and form one whole system.
Libido, arousal and as a consequence orgasm
Sex drive or libido depends on a biologically correct function of the glands of internal secretion, the testes in men and the ovaries in women, the adrenal glands in both sexes and is caused by the metabolism. And, of course, sexual desire, arousal and orgasm can be achieved without the participation, and the normal functioning of the brain.
Adult healthy people the degree of excitability of the sexual centers, as well as the strength of the sexual desire to take to determine the level of hormones.
There is an absolute dependence on sexual desire anthropological differences, for example, blondes, and blacks have a stronger sex drive than blondes. Another example people don't have the high-growth sexual attraction can be stronger than the high. Women asthenic physique, to achieve orgasm requires more foreplay or other effort than normal. People in southern countries with warmer climates libido brighter and stronger. The temperament of the southerners actually are actively developed than the north.
Of course, the sexual excitability of men and women are completely different. Number of sexual arousal in women is lower than men's. Man, I usually appears before a direct contact, sexual intercourse arousal grows very quickly, and an erection happens very quickly, and after the resolution of sexual arousal and of course, the erection disappears completely.
In addition, various hormones and erotic foreplay, stimulate sexual function can and some of the key stimuli.
This kind of sexual stimuli is purely individual for each person and personally, because of its presentation of sex, his sexual experiences and his sexual ideals.
Affect sexual arousal is capable of music in the first place, exerting a stimulating effect on the deep structure of the brain and he knows how to awake memories of erotic Association and other sexual experiences
Women are able to respond to the psycho-emotional impact of pathogens is slightly weaker than that of men.
Many women have the expectation of sexual contact may not cause sexual arousal, but most of the men in anticipation of sexual contact is a strong sexual arousal.
It is important to remember that the nature of male and female sexuality differ considerably.
Inter alia, sexual arousal can be caused not only under the action of certain hormones and pathogens, but also under the influence of a purely mechanical stimuli, and that different kinds of stimulation and stimulants, sexual affection and touch certain areas that are particularly sensitive to touch.
Well-known American sexologists masters W. and Johnson V. in the implementation of sexual arousal secrete some phase of excitation, i.e. the plateau-phase, the phase of orgasm and the stage, the so-called reverse development.
In the first stage, the stage of sexual arousal in normal men after a short period of time, usually up to thirty seconds, from the beginning of sexual stimulation, increases blood flow to the organs of the pelvis, and the difficulty of outflow of blood due to some compression of the veins. This leads to a sharp increase in penis size, growth is typically two to three times the penis becomes hardness, and significantly lengthened to seven or eight inches long. When an erection happened, the man immediately began to look for the release of sexual tension, a certain discharge.
If the friction on the nerve endings of the penis the vaginal walls during intercourse, the frequency of contact is sufficient, the erection will constantly grow, and sexual excitement will increase. Men becomes more frequent breathing and strengthen the heartbeat may become red in the face.
If you suddenly stop contact, so sexual arousal can fairly quickly and sometimes quite slowly weakened veins expand, the blood flow increases. This in turn leads to a reduction in penis size, and his fall. If the contact is restored, and the erection can quickly back.
After all for anybody not a secret that women need much longer time to prepare for intercourse, and the influence of his erogenous zones need much longer, that can cause enough sexual tension, and be able to admit to singing in the vagina.
Of course, some women are more emotional, they are very high secretory activity of the ovaries, these women are unable to achieve discharge even faster than some men.
However, the average woman with an average temperament, much harder to initiate sexual intercourse than a man, and there is not adequate foreplay, the sexual organs in women can be ready for sexual intercourse, the vaginal walls are almost closed, tight enough to each other, the lubrication is missing yet, flexibility is not yet developed. Sexual arousal in women can appear and grow only in the preliminary, sometimes quite a long-lasting effect on her erogenous zones.
Stage of sexual arousal in women is very similar to the excitement phase in men. Also increases blood flow to the pelvic organs. The labia minora increase in size and also two or three times, they are changing color from pale pink they can become almost a bright red. The clitoris is also swell, which is also called women's sexual feelings, it is able to increase one and a half, sometimes twice, when the penis, the clitoris becomes compacted. As well loose, you will become sexually excited, the vagina, blood vessels, the vagina fills with blood, it is hot, the muscles begin to involuntarily shrink shrink several vagina, which in turn promotes more intimate contact and friction of the male penis during sexual intercourse.
In addition to the above, during strong sexual arousal in the sex organs women get enough moisture, in the vagina secrete lubricant as necessary, which can facilitate pushing the penis into the vagina.
But when a calm state women's vaginal walls so closely adhere to each other, it remains only a small gap. Mode of sexual arousal, the vagina lengthens and dilates, the cervix will hang up and back. The diameter of the vagina also add to the vagina appear free location that can accommodate semen.
When there is an increase of tension, and this feeling reaches the desired height, and then held in this state for some time, you know - this is the plateau phase. This is the stage where the vagina adapts to the shape and size of the penis. Partners clearly feel the body each other. A woman's vagina, or rather its third component, can reduce by half, if you compare its dimensions to the dimensions in the previous step, and having the appearance of a narrow tube. The muscles of the female vagina, sufficiently sexual arousal tightly covers the penis. Thus, there is a strong stimulation of bodies, or rather their nerve endings for both partners.
This is the stage when a woman's breast to grow, there is a seal or erection of the nipples, they may even be lengthened to one centimeters, and add a half inch in diameter.
It sexologists masters W. and Johnson V. describe the orgasm in this way. Orgasm is approaching, when the outer third of the vagina begins rhythmic contractions. Such rhythmic contractions affect the muscles of the uterus. The vagina is the possibility of the contract at intervals of eight-tenths of a second. Depending on the number and intensity of the rhythmical contractions of orgasm either glamorous or peaceful. Typically, if you exercise three to five contractions orgasm is considered weak in the presence of six to eight contractions of the orgasm is the average intensity, from nine to twelve contractions, very strong orgasm. But these calculations are also very subjective, because there are women who experience orgasm extraordinary strength and intensity in just three to five cuts.
At the onset of orgasm in men is more often the number of respiratory movements, the pulse quickens. Achieve a hundred and eighty beats per minute, increases blood pressure may rise to twenty, and sometimes more points. For example, the male orgasm can increase the normal pressure of a hundred and twenty millimeters of mercury, two hundred. Currently, to achieve orgasm can be redness on the face and even Breasts.
In particular, varying the intensity can have an orgasm. It can be similar to that of men, short character, of course, and maybe vice versa to be prolonged and deep, gives indescribable bliss.
The female orgasm can be more than lingering, it can last twenty to sixty seconds, sometimes even longer. Protracted orgasm can be wavy nature of the flow, it increases, then decreases, and is still an unknown number of tens of seconds, sometimes it can be up to one and a half hours.
Find a number of women can experience multiple orgasms often repeated, which can follow each other at intervals of only one to two minutes. These women are capable of experiencing three, and even four orgasms during one sexual intercourse.
There are cases when a woman can be happy only when she will experience multiple, continuously following one after another orgasms, ten-twenty times. Most such repetitive orgasms happen in the active stimulation of the clitoris.
If a man has certain abilities of his partner, experience repeated orgasms in a row, he'll have to control myself not to ejaculate, as this may lead to the fact that his partner may remain unsatisfied with only one orgasm.
That's why women with long-term type of course orgasm, or in need of multiple orgasms partner, when it is not restrained, because the alternative would be to help partners, continue to promote the clitoris.
After orgasm a woman's body as something like that happens ejaculation. Currently some of the open cervix, and it unravels something in the plug of viscous mucus, the woman's seed, or secret uterine glands. The woman's seed, as if gently stroking a number of nerve endings, and it all adds spice to the feeling. After that, the plug of mucus rises in the back of the uterus and the cervix closes tightly. After ejaculation, when men and women disappear in the intense sensations in the genital tract, the outflow of blood, everywhere.
Even if the woman thought that he felt as if something squeezed it from the body, believe that female ejaculation exists, is subjective and not proven.
Leading sexologists argue about it for years, but these discussions have only theoretical value. But in practice, the woman has an orgasm, no idea. As this process is called ejaculation, orgasm, or something else. The most important thing is that he is immensely like.
The woman decided to share the five stages of the copulatory cycle are arranged in series:
- The psychic phase covers the time interval from the moment when a woman felt the desire to coition, and until he decides to implement his wishes;
- The sensory stage (from lat., Sens, meaning, feeling, sensitivity). Restructuring the perceptual quality, the increased reactivity of the erogenous zones, and their need in particular to promote;
- Secretory phase is characterized by the appearance of moisturizing and lubricating secretions in the vagina;
- The Orgasmic stage, in this stage, the woman gets the best pleasure of sweet sensations or orgasm;
- Relictum stage, this stage begins weakening of sexual arousal and the outflow of blood flow to the genitals.
Inter alia, during sexual intercourse are distinguishable from the mission, or the introduction of the penis into the vagina, stage translational movements or friction, and the stage, ejaculation and orgasm.
Many women find sexual intercourse climax of the emotionally demanding interpersonal relationship with a partner, they used to consider sex is not just physical intimacy, but also the spiritual convergence of a loved one.
