When it comes to the first night, many people immediately think of women for the first time. They all think that women’s first night is bleeding. In fact, the first night bleeding is not a woman’s patent. The first time a man will have a red-hot situation, but only a few people fall into the night, but less does not mean that it does not exist. Nowadays, people’s concept of sex is already very open, and the perception of women’s early nights has gradually faded. However, male sex is red, but it is especially scary for men. Too long foreskin can cause men’s bleeding after sexual intercourse, which is roughly caused by the foreskin being too long or too tight or the foreskin strap under the glans to be too short and too tight. If there is still a loose foreskin after the penis is erected, this part of the skin is easily bleed by repeated friction, especially when the vagina is not sufficiently lubricated. When the foreskin is too long, it often causes eczema and inflammation of the glans and foreskin, and it is more likely to bleed during sexual intercourse. The front end of the foreskin is too tight. In addition, the front end of the foreskin is too tight. When the penis is erected, the glans cannot still show its head. This kind of foreskin is more likely to cause laceration and bleeding during sexual intercourse. Sometimes this kind of foreskin will be stuck too hard after being forced to the back of the glans, causing the so-called incarcerated phimosis, the foreskin glans will be swollen and even necrotic, and then it can be solved without bleeding. At this time, it must be treated immediately. If the foreskin cannot be reset, the foreskin must be cut or removed immediately. Otherwise there will be unfortunate consequences.
