Orgasm, which is usually accompanied by ejaculation for a man, is the culminating stage of sexual arousal.
Ejaculation cannot be stopped once it has started, for it is an involuntary process of muscular contraction and release of tension. But a man can control how soon he ejaculates during sex in a variety of ways. He can increase the pressure on his penis by making deeper or harder thrusts during intercourse, or by more vigorous hand movements during masturbation, or by having his partner massage his prostate through the perineum or through the internal wall of the rectum via a finger inserted through the anus.
Another way is to contract the internal muscles which run through from his pelvic bone to his penis, a movement which will both speed up ejaculation and make it more intense. Learning to contract and therefore strengthen these muscles will result in much more intense orgasms and a much more powerful ejaculation.
Once the level of stimulation has reached such a point that the final phase of sexual arousal begins, your body prepares itself for orgasm in all kinds of ways. Your blood pressure goes up, your heart rate rises, your breathing becomes deeper and heavier, and there are involuntary contractions of muscles throughout your body, producing a desire to thrust deeper into your partner.
Immediately prior to ejaculation itself, seminal fluid builds up in the prostate gland. This produces that familiar sense of impending ejaculation – that moment where you just know you are going to ejaculate and nothing will stop it.
Then, at the moment of ejaculation, your testicles are drawn up close to your body, the urinary tract to your bladder closes so that your semen will spurt out of your penis rather than being passed back into your bladder, and the muscular contractions of your ejaculation take place.
These contractions involve the muscles at the base of the penis, the muscles of the penis shaft, the muscles around the anal sphincter, the pubococcygeus muscle, and the muscles of the rectum. They contract about eight times, maybe slightly more or less, at 0.8 second intervals, and as they do so the seminal fluid containing sperm is expelled. These contractions may lead to semen shooting out or just dribbling from the tip of your penis, depending on the condition of the muscles, how long it is since you last ejaculated, and the volume of fluid which has accumulated during the earlier phases of your sexual arousal.
Orgasm is the sensation that accompanies the ejaculatory contractions. It can be an energy flow, a sense of muscular contraction, an overall feeling of well-being.
