Ejaculation
Short definition:
Ejaculation designates the expulsion of sperm by the man. It is the result of repeated stimulation of the penis during intercourse or masturbation. We speak of the ejaculatory reflex. It also characterizes the male orgasm.
How does ejaculation work?

> Initially, the vas deferens (coming from the testicles) expel the spermatozoa towards the prostate, following sexual arousal. Then the seminal fluid, mixed with the spermatozoa, is expelled from the prostate and seminal vesicles and goes towards the base of the 'urethra. The man feels a tension that signals that he is about to reach orgasm. He has reached the point of no return.

The sperm is expelled. The ejaculation is accompanied by very powerful rhythmic contractions, caused by the muscles of the penis base and lower abdomen. In all, the man experiences 4 to 8 muscle contractions, and at the same time, he experiences an orgasm.
Warning: the sperm comes out with a relatively intense force. Most women experience this shake in the vagina.

Disorders of ejaculation
Premature ejaculation. It is a frequent but not serious problem. It affects about 1 in 3 men. Men (usually quite young) ejaculate at the onset of penetration and sometimes even earlier. Premature ejaculation is mainly caused by a problem with 'self control. Ejaculation becomes an uncontrollable reflex that the man cannot delay in order to make his pleasure last.
Anjaculation: no sperm comes out during ejaculation. In particular, this is the effect of some treatments used against cancer.
Retrograde or dry ejaculation: semen flows back into the bladder rather than being expelled. This abnormality is often caused by certain surgeries. And causes infertility.
Bloody ejaculation: the semen contains traces of blood. Often this disorder is benign but can sometimes indicate the presence of prostate cancer or certain infections.
Painful ejaculation: men experience pain in the urethra, pelvis or anus, caused by a prostate infection.
Two ejaculations in tow, is it possible?
From 30 to 45 minutes: this is the average waiting time after which a new ejaculation is possible. After ejaculation, the penis gradually loses its rigidity and it is rare for two ejaculations to occur in a row. This is due to several factors, such as the level of arousal and concentration, and the ability not to fall asleep. Rest assured, therefore, it is not your fault that he collapses immediately after making love! pituitary gland, a brain gland, secretes sleep-inducing endorphins.
Can you control your ejaculation?
In general, controlling ejaculation becomes easier with age. There are methods for learning to control pleasure, useful for men suffering from premature ejaculation, but also for others:
The "cold shower" effect: think of something not very erotic to delay the arrival of orgasm ...
you can also masturbate before intercourse to reduce arousal at the fateful moment.
Condoms retardants: they are useful for everyone, and not just for remedying premature ejaculations.
> The "start and stop" method. This American technique consists in asking the partner to apply pressure on the frenulum of the penis when the man feels that he will reach the point of no return.
Erection and ejaculation: two distinct processes
It is important to know that ejaculation is separate from the erection, the latter being controlled by the pituitary. There may therefore be ejaculations without erection, but also ejaculations without orgasm, as in the occasion of nocturnal ejaculations. Yes, during the night, our companions can ejaculate, but without necessarily having erotic dreams. Nocturnal ejaculations are more frequent in young people, which could be linked to the high rate of testosterone; however, the real cause of this phenomenon has not yet been found. In any case, during periods of abstinence from sexual intercourse, nocturnal ejaculation episodes are more frequent.
