$sexreeducated: The sexual response cycle has four phases: excitement, plateau, orgasm, and resolution. All genders experience these phases, although the timing usually is different. For example, it is unlikely that both partners will reach orgasm at the same time. In addition, the intensity of the response and the time spent in each phase varies from person to person. Understanding these differences may help partners better understand one another’s bodies and responses, and enhance the sexual experience. Phase 1: Excitement General characteristics of the excitement phase, which can last from a few minutes to several hours, include the following: Muscle tension increases. Heart rate quickens and breathing is accelerated. Skin may become flushed (blotches of redness appear on the chest and back). Nipples become hardened or erect. Blood flow to the genitals increases, resulting in swelling of the woman’s clitoris and labia minora (inner lips), and erection of the man’s penis. Vaginal lubrication begins. The woman’s breasts become fuller and the vaginal walls begin to swell. The man’s testicles swell, his scrotum tightens, and he begins secreting a lubricating liquid. Phase 2: Plateau General characteristics of the plateau phase, which extends to the brink of orgasm, include the following: The changes begun in phase 1 are intensified. The vagina continues to swell from increased blood flow, and the vaginal walls turn a dark purple. The woman’s clitoris becomes highly sensitive (may even be painful to touch) and retracts under the clitoral hood to avoid direct stimulation from the penis. The man’s testicles are withdrawn up into the scrotum. Breathing, heart rate, and blood pressure continue to increase. Muscle spasms may begin in the feet, face, and hands. Muscle tension increases. Phase 3: Orgasm The orgasm is the climax of the sexual response cycle. It is the shortest of the phases and generally lasts only a few seconds. General characteristics of this phase include the following: Involuntary muscle contractions begin. Blood pressure, heart rate, and breathing are at their highest rates, with a rapid intake of oxygen. Muscles in the feet spasm. There is a sudden, forceful release of sexual tension. In women, the muscles of the vagina contract. The uterus also undergoes rhythmic contractions. In men, rhythmic contractions of the muscles at the base of the penis result in the ejaculation of semen. A rash, or “sex flush” may appear over the entire body. Phase 4: Resolution During resolution, the body slowly returns to its normal level of functioning, and swelled and erect body parts return to their previous size and color. This phase is marked by a general sense of well-being, enhanced intimacy and, often, fatigue. Some women are capable of a rapid return to the orgasm phase with further sexual stimulation and may experience multiple orgasms. Men need recovery time after orgasm, called a refractory period, during which they cannot reach orgasm again. The duration of the refractory period varies among men and usually lengthens with advancing age. Do remember: Not all women have a vagina and not all men have a penis.$

The sexual response cycle has four phases: excitement, plateau, orgasm, and resolution. All genders experience these phases, although the timing usually is different. For example, it is unlikely that both partners will reach orgasm at the same time. In addition, the intensity of the response and the time spent in each phase varies from person to person. Understanding these differences may help partners better understand one another’s bodies and responses, and enhance the sexual experience.

Phase 1: Excitement

General characteristics of the excitement phase, which can last from a few minutes to several hours, include the following:

Muscle tension increases.

Heart rate quickens and breathing is accelerated.

Skin may become flushed (blotches of redness appear on the chest and back).

Nipples become hardened or erect.

Blood flow to the genitals increases, resulting in swelling of the woman’s clitoris and labia minora (inner lips), and erection of the man’s penis.

Vaginal lubrication begins.

The woman’s breasts become fuller and the vaginal walls begin to swell.

The man’s testicles swell, his scrotum tightens, and he begins secreting a lubricating liquid.

Phase 2: Plateau

General characteristics of the plateau phase, which extends to the brink of orgasm, include the following:

The changes begun in phase 1 are intensified.

The vagina continues to swell from increased blood flow, and the vaginal walls turn a dark purple.

The woman’s clitoris becomes highly sensitive (may even be painful to touch) and retracts under the clitoral hood to avoid direct stimulation from the penis.

The man’s testicles are withdrawn up into the scrotum.

Breathing, heart rate, and blood pressure continue to increase.

Muscle spasms may begin in the feet, face, and hands.

Muscle tension increases.

Phase 3: Orgasm

The orgasm is the climax of the sexual response cycle. It is the shortest of the phases and generally lasts only a few seconds. General characteristics of this phase include the following:

Involuntary muscle contractions begin.

Blood pressure, heart rate, and breathing are at their highest rates, with a rapid intake of oxygen.

Phase 4: Resolution

During resolution, the body slowly returns to its normal level of functioning, and swelled and erect body parts return to their previous size and color. This phase is marked by a general sense of well-being, enhanced intimacy and, often, fatigue.
