Physiologically, any person who passes through these phases of the sexual response cycle that built: sexual desire, sexual arousal, and as a result orgasm and resolution phase.
For the regulation of the functions of the sexual sphere of man, by nature, was created for organizations like the cerebral cortex as subcortical structures, and some centres of the spinal cord. All sex centers that regulate sexual function, they are closely linked, and, of course, are in clear interaction, only to obey, and form a single whole system.
Libido, arousal and as a result of the orgasm
The sexual desire or libido depends on a biologically correct for the activity of the glands of secretion internal 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 not be achieved without the participation, and the normal functioning of the brain.
In a healthy adult person, the degree of excitability of the sexual centres, as well as the strength of sexual desire taken to determine the level of hormones.
There is absolute dependence, of sexual desire of the anthropological differences, for example, brunettes, and blacks have a strong sexual desire blondes. Another example in humans is not a high growth of the sexual attraction can be stronger than the high. Women asthenic physique, to reach orgasm, this will require a greater amount foreplay or other effort than normal. People from southern countries with warmer climates libido brighter and stronger. The temperament of southerners really are more actively developed than the northerners.
Of course, the excitability sexual of men and women are fundamentally different. Often sexual arousal in women is lower than that of men. Male desire usually appears before a direct contact, in the course of the sexual relationship, the excitement growing very fast, and the erection occurs very quickly, and after the resolution of the sexual excitement and, of course, the erection disappears completely.
In addition to various hormones and erotic foreplay, stimulate sexual function can and some of the main stimuli.
This type of stimuli, the sex is purely individual for each person and, personally, due to its presentation of sex, their sexual experiences and their 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 she is able to arouse memories of erotic Association and other sexual experiences
Women are able to respond to the psycho-emotional impact of any pathogens is a bit weaker than men.
Often women have an expectation of sexual contact does not cause sexual arousal, but the majority of men, in anticipation of sexual contact is a great sexual excitement.
It is important to remember that the nature of male and female sexuality differ considerably.
Among other things, sexual arousal can be caused not only by the influence of certain hormones and pathogens, but also under the influence of the purely mechanical stimuli, and that different types of stimulation and stimulants, sexual affection, and touch to specific areas that are especially sensitive to the touch.
Renowned 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 phase of the so-called reverse development.
In the first phase, the phase of sexual arousal in normal men after a short period of time, usually up to thirty seconds, from the beginning of the sexual stimulation, to increase the flow of blood to the organs of the pelvis, and the difficulty of the exit of the blood due to some compression of the veins. That leads to a sharp increase the penis in size, the increase is typically two to three times the penis becomes hardness, and significantly extended seven or eight inches in length. Once erection has occurred, the male begins to look immediately for the release of the tension sexual, up to a certain download.
If the friction of the nerve endings of the penis into the vaginal walls during intercourse, the density of contact is sufficient, the erection constantly grow, and the sexual excitement will increase. Men become more frequent in the breathing and strengthen the heartbeat may become red in the face.
If you stop the contact, and then sexual arousal can very quickly and sometimes very slowly weakened veins expand, the blood flow will increase. That in turn will lead to the reduction in the size of the penis, and his fall. If the contact is restored, and an erection is able to recover quickly.
After all for anybody not a secret that women need much more time to prepare for intercourse, and affect her erogenous zones need much more time that will be able to cause a sufficient degree of sexual excitement, and be able to recognise the singing of the vagina.
Of course, some women are more emotional, have a very high secretory activity of the ovaries, these women are not able to get the download even faster than some men.
However, the average woman with an average temperament, much more difficult to start the sexual relations of a man, and in the absence of enough foreplay sex organs in women may not be prepared for sexual intercourse, the vaginal walls are almost closed, enough adjusted to the other, the lubrication is still missing, the elasticity is not yet developed. The Sexual arousal of women can appear and grow only in the draft, sometimes very long duration of the impact on the erogenous zones.
Phase of sexual arousal of women is very similar to the excitement phase in men. It also increases the blood flow to the organs pelvic. The lips will increase in size and also in two or three times, they, changing color from pale pink that can come to be almost bright red. The clitoris will also swell, also called a women's sexual feelings, it is capable of increasing an hour and a half, sometimes twice as the penis, the clitoris will become compacted. As well loose becomes sexually excited, the vagina, the blood vessels of the vagina fills with blood, it is converted into heat, the muscles begin to involuntarily shrink shrink several vagina, which in turn will contribute to a more intimate contact and friction with the male penis during sexual intercourse.
In addition to the above, during strong sexual excitement sexual organs of women gain enough moisture, the vagina secretes lubricant as needed, which is capable of facilitating the sliding of the penis into the vagina.
But when a calm state of women of the vaginal walls, so closely united between themselves, there remains only a small gap. In a state of sexual arousal the vagina will lengthen and expand, the cervix will hang up and return. The diameter of the vagina also increase in the vagina will appear for a free site that will accommodate semen.
When there is a surge of emotion, and this feeling reaches the desired elevation, and then remains in this state for a certain period of time, know - this is the plateau phase. This is the phase in which the vagina adapts to the shape and size of the penis. Partners clearly feel the body of another. Woman the vagina, or rather its third part, is able to reduce by half, if we compare its dimensions with the dimensions in the previous phase, and it leads to the appearance of a narrow tube. The muscles of the vagina in the female, with the sufficient sexual arousal tightly cover the penis. There is, therefore, a potent stimulus of bodies, or rather their nerve endings for both partners.
This is the phase when the female breast increases, there is a seal or erection of nipples, they can even be elongated by a centimeter and increase in diameter to half an inch.
The sexologists, masters W. and Johnson V. describe the female orgasm in this way. The orgasm is approaching, when the rest of the third of the vagina begins contractions rhythmic. These contractions rhythmic affect the muscles of the uterus. The vagina is able to contract at intervals of eight-tenths of a second. Depending on the quantity and the intensity of the contractions rhythmic orgasm will either be charming or calm. Normally, if the exercise of three to five contractions orgasm is considered to be weak in the presence of six to eight contractions orgasm is the average of the intensity, of nine to twelve contractions, very strong orgasm. But these calculations are also very subjective, as there are women experiencing orgasm extraordinary strength and intensity in only three of the five cuts.
At the beginning of the orgasm in men becomes more frequent the number of movements or breathing, the pulse quickens. Arrive at one hundred eighty beats per minute, increase of arterial pressure can be up to twenty, and sometimes more points. For example, a male orgasm can increase the pressure from normal to one hundred and twenty millimeters of mercury, to two hundred. At the time of reaching orgasm may be redness of the face and even Breasts.
Especially variable in intensity, may be the female orgasm. May be similar to that of men, with a brief character of course, and perhaps Vice versa, to be prolonged and deep, giving a joy indescribable.
The female orgasm can be more persistent, can last twenty to sixty seconds, sometimes even more. A prolonged form of the orgasm can have a character wave motion of flow, that increases, and then decreases, and continues an unknown number of tens of seconds, sometimes it can be even an hour and a half.
Found a number of women who can experience multiple orgasms repeated, that you can follow with an interval of only one or two minutes. These women are capable of experiencing three, and even four orgasms during one sexual contact.
There are cases in which a woman can feel satisfied only when she will experience multiple, continuously following one after another of orgasms, from ten to twenty times. The majority of such repetitive orgasms happen with the active participation of stimulation of the clitoris.
If a man of trust in the capabilities of their partner, to experience repeated orgasms in a row, he will have to refrain myself not to ejaculate, as this can lead to the fact that your partner may be satisfied with only one orgasm.
Therefore, for women with prolonged type of course orgasm, or needs multiple orgasms partner, in the cases in which is not restricted, as the option that has to help the couple, in addition to the stimulation of the clitoris.
When the orgasm in the body of a woman as a thing, as what happens in the ejaculation. In this moment opens the neck of the womb, and from it erupts something like the plug of mucus viscous, the women of the seed, or secret uterine glands. The women of the seed as if stroking gently multiple nerve endings, and it all adds salt to the sensation. After this, the plug of mucus climbs back into the uterus and the cervix closes tightly. After the ejaculation, as men and women disappear intense sensations in the genital organs, the exit of the blood, of everything.
Even if a woman think that she feels like something difficulties in your body, the vision of the female ejaculation exists, it is subjective and not proven.
The main sexologists argue about this for years, but these discussions have only theoretical value. But in practice, a woman getting an orgasm absolutely no idea. As this process is called ejaculation, orgasm, or something else. The important thing is that she is very similar.
The women decided to allocate five stages of the copulatory cycle arranged in series:
- The psychic phase covers the time interval from the moment when the woman he felt the desire of sexual intercourse, and until that is decided by you to carry out your wishes;
- The sensory stage (from lat., Of course, that means feeling, sensitivity). A restructuring of the perception of the quality, the increased the reactivity erogenous zones, and the need for them specifically to stimulate;
- The secretory stage is characterized by the appearance of a hydrating and lubricating secretions of the vagina;
- Orgasmic stage, in this stage, the woman gets the best pleasure of sweet sensations or orgasm;
- Relictum stage, during this stage begins weakening of sexual arousal and the output of the blood circulation in the genital organs.
Among other things during sexual intercourse are distinguishable missio, or the introduction of the penis into the vagina, stage translational movements or frictions, and the stage of ejaculation and orgasm.
Many women consider sexual intercourse as the culmination of an emotionally demanding interpersonal relationship with the partner, they used to consider sex not only as physical proximity, but also as a spiritual rapprochement with a loved one.
