The experience of orgasm is similar for men and women. Pleasure builds until you feel a sense of inevitability, at which point your skin flushes, pulse accelerates, and breathing quickens. As the wave of tension and release surges through you, your muscles clench and spasm. Vaginal and anal muscles contract, squeezing the penis or other penetrating objects even more tightly than before, and the man’s throbbing erection may bounce up and down as it ejaculates.
Men can reach orgasm within a few minutes of intercourse or masturbation, or even faster if they are highly aroused. Women benefit from longer foreplay and stimulation of multiple erogenous sites.
By the time a man reaches the point of inevitability, spermatic fluids have accumulated in the prostate and other glands and ducts, from which they are forcefully ejected in a series of muscular contractions. The head of the penis becomes uncomfortably sensitive to touch during and after orgasm, so he may need to stop thrusting or withdraw his penis. If you are jerking or sucking a penis when the man starts to come, you should adjust the pace and tightness of your grip; do not squeeze harder or you may stymie the ejaculation.
Male ejaculate consists of sperm floating in a mixture of cholesterol, sugars, salts and protein, which has a sweet and salty taste and a faint smell of chlorine. Semen can vary in consistency from watery to gelatinous (or a mix of both), and the volume depends in part on the length of arousal and the number of days since the last ejaculation. A tablespoon is a typical amount, and maximum volume is reached after about five days. A thinner, slippery “pre-come” may also drip from the tip of the penis during arousal, and this contributes to lubrication during intercourse. Women also exude lubricating fluids and may ejaculate a small amount from the pee-hole at the time of orgasm.
Men experience a refractory period after orgasm, during which it is difficult to become erect again, and this refractory period becomes longer and longer with age. (Adolescents and young adults may be able to get hard again within a few minutes if they are sufficiently psychologically aroused.) Women have an advantage over men in their ability to reach orgasm multiple times in succession.
