The curse of long sex.

Testosterone is a male sex hormone that makes it possible to maintain libido and erection. The amount of testosterone decreases - both the erotic mood and excitability decrease, the time of sexual intercourse increases. At first, these men experience difficult ejaculation. It is difficult for him to cum and get an orgasm. At the same time, there is an erection, but there is still no ejaculation. With an even greater drop in testosterone concentration, the ability to complete sexual intercourse is generally lost. In addition, the amount of sperm depends on the amount of testosterone.
