Too long prepuce will generally cause the following problems: 1, which is easy to cause premature ejaculation: the glans mucosa is usually hidden under the prepuce, and the glans mucosa is usually less rubbed and stimulated, which makes the nerve sensation of the glans mucosa too sensitive. When making love, the glans is exposed after the penis is erect. When the glans penis and vagina are stimulated by friction, the nerve of glans penis mucosa is too sensitive, which triggers premature ejaculation and causes premature ejaculation. 2, easy to cause ejaculation: the glans penis is overprotected by the skin, the rich nerve conduction stimulation and stimulation excitement function of the glans penis disappears, and the harm of long foreskin can not reach the stimulation intensity needed to stimulate ejaculation in sexual life, so it is easy to not ejaculate. 3, easy to cause cancer: if the foreskin is too long, there will be scales, leading to penile cancer in men and cervical cancer in women. 4, easy to cause infertility: some patients are prone to recurrent urethral orifice infection, causing adhesion between the foreskin and the glans mucosa, affecting the normal development of the glans and causing balanitis. It can be seen that the foreskin is too long, so we should go to a regular place to have a look. Personally, I think the Armed Police Benxi Fire Hospital is quite good. At least there will be no charge. It was when I used to go. The doctors there have a good service attitude. The hospital is located in the former Armed Police Fire Brigade (opposite to the Fire Labor Building). You can take a look sometime. I wish you a speedy recovery.
