The beginning of orgasm
Orgasm (the Greek "orgasmos", from "orgao" - a passionate passion) is the highest degree of voluptuous sensation at the moment of the completion of the sexual act or the forms of sexual activity that replace it. It is also called the highest point (top) or "klaymaksom".
Orgasm can manifest itself differently, not only in different people, but also in the same person. It can be an explosion of sensations, ecstasy, an avalanche, or maybe a kind of a softer and less intense reaction. As A. Bova and E. Savina write, "although the physiological parameters of all orgasms are similar, the perception of one orgasm may differ from another as a glass of cool water in the heat, when you suffer from thirst, is different from the drink offered to you in the usual state."
The different intensity of orgasm can be associated with physiological factors, for example, fatigue, short intervals between orgasms website about. The intensity of orgasm depends on psychological factors - moods, relationships between partners, emotional mood for sexual intercourse, anticipation of pleasure and attitude to sexual intercourse.
The beginning of orgasm is perceived by most men as a feeling of heat or pressure, sometimes with a ripple. This corresponds to the phase of "ejaculatory inevitability". Then the orgasm is felt as a fast, tremendous pleasure for contractions of the anal sphincter (anus), rectum, perineum and penis. This can be a sharp sensation or a feeling of "exhaustion". Or a man feels "a warm liquid ejection," a "shot", which corresponds to the exit of the sperm from the urethra.
In the phase of orgasm, both in men and in women, there is an increased strain of the muscles of the entire body. During orgasm, muscle spasms and limb spasms may occur. The tension of the muscles of the face manifests itself in the form of grimaces or frowning of the eyebrows. An inexperienced partner (sha) can accept such a distortion of the face as an expression of discontent, but in reality it is just an involuntary reaction.
And from these positions, the partner (sha) should perceive this "grimace" as evidence of a high level of sexual arousal, during which a person can not control his facial muscles.
And vice versa. If the partner simulates an orgasm, moans, moans and struggles in convulsions, but at the most critical moment she smiles and her expression "expresses" the expression of indescribable bliss - then this can give the man a reason to suspect her of pretending. Feelings of bliss, peace and tranquility on the woman's face the partner will be able to see later, after experiencing orgasm, but not during it. After this (and not simulated) orgasm, the woman is relaxed, she does not want to move, she wants to have bliss and tenderness. And if right after her imaginary convulsions she busily tells a man about some extraneous things, then this is also one of the indirect signs of an orgasmic simulation.
Orgasm in men differs from the orgasm of women not only in its duration (in men it is shorter) and in intensity (in men all sensations are sharper), but also by the presence of two distinct phases (they are described in the section on ejaculation). Unlike men, women do not have a stage of excitement that would correspond to the "inevitability of orgasm" in the male sexual response. Offensive orgasm in women can be interrupted by any distraction at any time. And if a man has reached the phase of "inevitability", then orgasm will come necessarily. Although the orgasms of the same men vary in intensity, but in general they are more monotonous than women.
Orgasm is the shortest phase of the copulatory cycle. It is characterized by a rhythmic contraction of the muscles, which causes strong sensations, after which the excitement in men rapidly decreases.
Orgasm in men usually lasts a few seconds. The type of orgasm, in which the power of voluptuous sensation quickly grows and quickly disappears, sexopathologists call piciform, or short-term orgasm. It is peculiar to men. But this type of orgasm, but longer than men, can be in women.
From the physiological point of view, orgasm is a period of satisfaction, when the human consciousness is directed inwards, to enjoyment. External stimuli are practically not perceived. Therefore, psychiatrists joke that orgasm is also one of the forms of disturbed consciousness previously, there were hypotheses that explained the nature of orgasm, based on its peripheral or central origin.
Hypotheses of the peripheral origin of an orgasm linked it to the contraction of ejaculating muscles or to the active overcoming of the seminal fluid by the narrow mouths of the vas deferens, which open into the posterior part of the urethra on the seminal tubercle.
Hypotheses of the central origin of orgasm associated it with irritation of the centers of the spinal cord or the so-called paraspinal (near the spinal cord) formations of the autonomic nervous system, or with the existence in the brain of a special center that, upon excitation, poured a specific "intoxication substance" onto the remaining cells of the brain. In GSVasilchenko's opinion, orgasm is the result of a complex interaction of a number of structural formations located at different levels (pelvic, spinal, diencephalic and cortical).
In the first phase of ejaculation (preorganic), due to the active overcoming of the seminal fluid by the seminal fluid of the narrow mouths of the vas deferens and its entry into the prostatic part of the urethra, impulses emerge that enter the higher centers of the brain and are initially perceived as a feeling of inevitability, impossibility to stop the impending wave of orgasm, Not yet as an orgasm.
In the second phase of orgasm, impulses from the prostatic part of the urethra go to the center of the brain (into the paracentral lobes). This center is sensitized (that is, has increased sensitivity) the sum of pulses from the erogenous zone of the glans penis. The integration (integration) of these impulses by the center in the brain after overcoming the threshold of the onset of orgasm causes a chain reaction that manifests itself in the strongest nerve discharge. Its motor component is realized in the form of a series of muscle spasms that run through the outer part of the urethra at intervals of 0.8 seconds, and is accompanied by the strongest sensory accompaniment.
Although normal ejaculation and orgasm occur simultaneously, however, sexopathologists share these two processes. Orgasm - is primarily a sharp rhythmic contraction of the muscles of the genital organs and other parts of the body. This ensures the removal of accumulation of sexual tension and the experience of voluptuous sensations. But orgasm can occur without ejaculation, and ejaculation can be without orgasm.
Vasilchenko explains the dissociation of orgasm and ejaculation from the position of the system concept. It implies functional unity of two levels: a) cerebral (from the word "cerebrum" - the brain), which combines the conditioned reflex complexes of the sexual sphere and certain parts of the brain, and b) segmental - that is, certain segments of the spinal cord - lumbar and sacral Departments of the ejaculation center. The segmental level, the functional substrate of ejaculation, is directly related to the motor manifestations that ensure the transition of the first preorganic phase of ejaculation to its second phase, which is closely related to orgasm. And the cerebral level is not associated with motor manifestations, but with sensations, realizing their perception, evaluation and integration.
This explains the presence of pollutions during sleep, when the inhibitory effect of the cerebral cortex is reduced. These pollutions may not be accompanied by orgasm, but are found only by traces of sperm on the laundry. Other cases of ejaculation without orgasm are possible.
And with an orgasm without ejaculation, there are reverse relationships: a sharp decrease (up to the complete functional paralysis) of the excitability of the lower segmental division along with functional preservation or even increased excitability at the cerebral (cerebral) level. Therefore, in some cases, orgasm is possible without ejaculation. Most often it happens in the presence of neglected chronic prostatitis (inflammation of the prostate gland).
Orgasm can arise both in sexual intercourse - a coital orgasm (from the word "coitus" - a sexual act), and without it - estracoital orgasm (for example, with pollutions, masturbation). An occasional mechanical irritation of the genital organs can lead to orgasm, for example, when climbing along a rope, riding a bicycle - a so-called accidental orgasm.
Orgasm has great biological significance. The sense of satisfaction from sexual intercourse is inherent in all mammals. It is characteristic of both representatives of cultural and primitive peoples.
Sexologists believe that the biological role of orgasm is not limited to the motive that leads to sexual intercourse. The basis of orgasm is an unconditioned reflex, which reinforces the entire sequence of sexual reactions, forming from a single manifestation a holistic psychophysiological act. In the process of intimacy, biological components and individual personal manifestations and behavior merge. This is the main role of orgasm.
A. Kinsi using a questionnaire found that men experience orgasm almost every time they have intercourse. However, Hunt found that 8% of married men over the age of 45 often do not experience orgasm.
