Generally speaking, men who do not have sex will not do anything, but some men who do not have sex for a long period of time may lead to prostatitis, decreased genital responsiveness and erectile dysfunction. 1. Prostatitis: men who do not have sex for a long time may not be able to discharge semen, which may lead to prostatitis, frequent urination, urinary urgency, and pain in the penile area. 2. Decreased genital responsiveness: If men do not have sex for a long time, it may lead to decreased genital responsiveness, liquefaction of sperm in the genitals, prolonged sperm storage and inflammation. 3. Erectile dysfunction: when the male body produces sexual desire, the brain will receive signals to stimulate the pituitary gland, which will increase the congestion of the penis. If the libido is suppressed for a long time, the penis may be resistant to stimulation and erectile dysfunction may occur. Also for married men, if they have not had sex for a long period of time, there is a risk that it may affect their relationship. For adults, sex is an important part of life, and a proper sex life can relax the body and mind and improve the sense of well-being. Of course, not having sex does not necessarily lead to damage to the body, and should be chosen appropriately in light of your own situation.
