Not having sex for a month does not usually affect your health. Usually a short period of time without sex has no effect on your health. However, some people may have certain effects on their health if they do not have sex for a long time. For women, not having sex for a long time may cause disorders in the secretion of sex hormones, inducing diseases such as dysmenorrhea, breast or mental illness. In addition, prolonged absence of sexual intercourse may also lead to a decrease in the secretion of vaginal mucus, which may reduce the resistance to germs. For men, prolonged absence of sexual intercourse may lead to symptoms such as rapid ejaculation and decreased erection hardness. It is recommended to take into account their own situation and rationally arrange their sex life, but also pay attention not to have excessive sex, which can also be mentally depleted and cause inflammation of the reproductive tract and so on. You should pay attention to hygiene during sex and avoid overwork.
