Excitement phase[ edit ] The excitement phase also known as the arousal phase or initial excitement phase is the first stage of the human sexual response cycle, which occurs as a result of physical or mental erotic stimulisuch as kissingmaking outfantasizing or viewing erotic imagesthat leads to sexual arousal.
During this stage, the body prepares for sexual intercourseinitially leading to the plateau phase. The sex flush tends to occur more often under warmer conditions and may not appear at all under cooler temperatures.

During the female sex flush, pinkish spots develop under the breasts, then spread to the breasts, torso, face, hands, soles of the feet, and possibly over the entire body. During the male sex flush, the coloration of the skin develops less consistently than in the female, but typically starts with the epigastrium upper abdomenspreads across the chest, then continues to the neck, face, forehead, back, and sometimes, shoulders and forearms.
L'ABC de l'excitation chez l'homme
The sex flush typically disappears soon after orgasm occurs, but this may take up to two hours or so and, sometimes, intense sweating will occur simultaneously. The flush usually diminishes in reverse of the order in which it appeared. Also, the external anal sphincter may contract randomly upon contact or later during orgasm without contact.
Excitement in males[ edit ] In males, the beginning of the excitement phase is observed when the penis becomes partially or fully erectoften after only a few seconds of erotic stimulation. Both testicles become drawn upward toward the perineumnotably in circumcised males where less skin is available to accommodate the erection. Also, the scrotum can tense and thicken during the erection process.

Excitement in females[ edit ] In females, the excitement phase can last from several minutes to several hours. The onset of vasocongestion results in swelling of the woman's clitoris, labia minora and vagina.
The muscle that surrounds the vaginal opening grows tighter and the uterus elevates and grows in size. The vaginal walls begin to produce a lubricating organic liquid.

See also: Edging sexual practice The plateau phase is the period of sexual excitement prior to orgasm. The phase is characterised by an increased circulation and heart rate in both sexes, increased sexual pleasure with increased stimulation and further increased muscle tension. Also, respiration continues at an elevated level.
Prolonged time in the plateau phase without progression to the orgasmic phase may result in sexual frustration. Plateau in males[ edit ] During this phase, the male urethral sphincter contracts so as to prevent urine from mixing with semenand to guard against retrograde ejaculation and muscles at the base of the penis begin a steady rhythmic contraction.
The clitoris becomes extremely sensitive and withdraws slightly, and the Bartholin glands produce further lubrication. The tissues of the outer third of the vagina swell, and the pubococcygeus muscle tightens, reducing the diameter of the opening of the vagina.

For those who never achieve orgasm, this is the peak of sexual excitement. Main article: Orgasm Orgasm is the conclusion of étapes du pénis dexcitation plateau phase of the sexual response cycle and is experienced by both males and females. It is accompanied by quick cycles of muscle contraction in the lower manque de pénis muscles, which surround both the anus and the primary sexual organs.
Women also experience uterine and vaginal contractions.

Orgasms are often associated with other involuntary actions, including vocalizations and muscular spasms in other areas of the body and a generally euphoric sensation.
Heart rate is increased even further. Each ejection is accompanied with continuous pulses of sexual pleasure, étapes du pénis dexcitation in the penis and loins.

Érection avec rien first and second convulsions are usually the most intense in sensation and produce the greatest quantity of semen.
Thereafter, each contraction is associated with a diminishing volume of semen and a milder sensation of pleasure.
Au commencement est le désir. Chez la femme : les parois du vagin se tendent et ce dernier libère un liquide lubrifiant. Pour éviter une éjaculation incontrôlée, il faut alors éviter toutes stimulations.
They are commonly associated with an increase in vaginal lubrication, a tightening of the vaginal walls and overall pleasure. Resolution in males[ edit ] Masters and Johnson described the two-stage detumescence of the penis: In the first stage, the penis decreases from its erect state to about 50 percent larger than its flaccid state.
This occurs during the refractory period. In the second stage and after the refractory period is finishedthe penis decreases in size and returns to being flaccid. As a result, they are able to have multiple orgasms in a relatively short period of time.

This leads to swelling of the penis above or clitoris and labia below. Masters and Johnson argue that, despite some minor differences, sexual responses in both men and women are fundamentally similar. First, Masters and Johnson put forth one model for men, but étapes du pénis dexcitation different models for women. They stated that énurésie et érection sexual response only differs in terms of duration; showing different models would, thus, be repetitive.
Women, on the other hand, they state can have responses that differ in both intensity and duration. A woman's clitoris is the anatomical parallel to a man's penis.
As a result, clitoral swelling would be the equivalent of a man's erection. Research by Meredith L. Chivers and J. Michael Bailey indicates that men tend to show category-specific arousal; that is, they are sexually aroused by their preferred gender.
However, women show category non-specificity: Their genitals show arousal to both preferred and non-preferred genders. However, inaccuracies have been found in the descriptions of the stages of sexual response. For example, Roy Levin identified a few areas of the model that had not been touched upon. Levin also presents research which shows that the first signs of physiological arousal in women is increased blood flow to the vagina, not lubrication. He also dispels information about men and their sexual response; Masters and Johnson report that pleasure was positively associated with the volume of ejaculate released, but Rosenberg, Hazzard, Tallman and Ohl gave a group étapes du pénis dexcitation men a questionnaire and found that significantly more men reported that physical pleasure was associated with the strength of the ejaculation compared to the volume.

For example, Helen Singer Kaplan argued that Masters and Johnson only evaluated sexual response from a physiological perspective, and that psychological, emotional, and cognitive factors need to be taken into consideration.
As a result, she proposed her model of the sexual response cycle which includes three phases: desire, excitement, and orgasm.
She argues that these three phases are interconnected, yet they have different neurophysiological mechanisms. The model explains that the desire for sex comes from an interaction between a sensitive sexual response system and stimuli that are present in the environment.
Researchers argue that this model supports the idea that sexual desire is not spontaneous. Furthermore, this model implies that the case is not that one has sex because one feels sexual desire; rather, the case is that one feels sexual desire because one has sex. She argues that the linear model is good at explaining men's sexual response but it poorly explains women's sexual responses; thus, she puts forth a circular model.
This leads to enhanced sexual arousal, which may ultimately result in orgasm. Consequently, this positive sexual arousal continues the sexual desire that women feel, and this desire increases intimacy with the partner.

In one study conducted by Giles and McCabe, they found that the linear model of sexual response was a good predictor of women's sexual functioning and dysfunctionwhile the circular model was a poor predictor.
