What are the stages of ejaculation?

Answer 1

Phase 1 of the Male Sexual Response - Excitement In response to sexual stimuli (whether psychological in the form of sexual thoughts or fantasies, or physical in the form of physical stimulation) the process of vasocongestion occurs, where more blood flows into the penis than is flowing out, and the result will usually be that a man will get an erection. How long this takes, and what the erection feels like will differ from man to man, and for the same man over time.

Physical changes may include: -There are also changes in the scrotum and testes, with the testes increasing in size and the scrotum elevating, coming closer to the body.

-The skin may become flushed; men may experience heightened sensitivity in parts of their body, like the nipples.

-Some increase in heart rate, blood pressure, and muscle tension.

Phase 2 of the Male Sexual Response - Plateau With continued sexual stimulation this phase represents the time between the initial arousal and excitement, up until orgasm. For many men the plateau phase is very short, but this is the phase that men can extend as a way of controlling premature ejaculation.

Physical changes during this phase may include: -An increase in the size of the head of the penis, and the head may also change color, becoming purplish.

-The Cowper's gland secretes fluid, often referred to as pre-cum, which comes out of the tip of the penis.

-The testes move further in towards the body, and increase in size.

-There may be a sex flush, muscle tension, increase in heart rate and rising blood pressure.

Phase 3 of the Male Sexual Response - Orgasm Masters and Johnson further divided the orgasmic phase for men into two separate stages. In the first stage: -Contractions in the vas deferens, seminal vesicles, and the prostate causes seminal fluid ("come" or ejaculate) to collect in a pool at the base of the penis, in the urethra. This collection is usually felt as a "tickling" type sensation. In the second stage of the orgasmic phase:

-Contractions of muscles occur in a "throbbing" manner around the urethra, and propel ejaculate through the urethra and out of the body.

-These contractions (which occur at different speeds, and in different amounts) are usually what are experienced as highly pleasurable feelings of release. Phase 4 of the Male Sexual Response - Resolution

Resolution phase refers to the period of time immediately following an orgasm, when the body begins to return to its "normal" state. This phase includes:

-The loss of the erection as the blood flows out of the penis, which happens in two stages over the period of a few minutes.

-The scrotum and testes return to normal size.

-A general feeling of relaxation.

Answer 2

There is a four-stage model to diagram the human sexual response to sexual stimulation:

1. Excitement - there are physiological changes that can be witnessed in both genders; there is an increase in heart rate and breathing rate, and arousal of the erogenous zones.
2. Plateau - this is the phase immediately before orgasm; further sympathetic responses occur, including a tightening of the muscles.
3. Orgasm - conclusion to the plateau; involves contraction of pelvic muscles (and ejaculation in males).
4. Resolution/refractory period - body slows down, muscles relax (parasympathetic); males cannot readily go back to excitement phase (nor can females, but refractory period is shorter for women).

Answer 3

The stages of ejaculation typically include arousal, plateau, orgasm, and resolution. During arousal, sexual stimulation causes blood flow to the genitals. The plateau phase involves an increase in arousal leading up to orgasm. Orgasm is the peak of sexual pleasure, accompanied by involuntary muscle contractions. Resolution follows, with a decrease in arousal and relaxation of the body.
