Sexual health care is one of the most important and most neglected topics for men. When they have all kinds of problems in their sex life, sexual function also needs health care and care, there are several key periods that need special attention. The first: puberty and post-pubertal (16-24 years old) men enter puberty, the physiology will undergo huge changes, androgen levels can even increase forty to fifty times, the emergence of sexual desire, erection, sexual fantasy, dreaming, etc.. The first thing to understand is that masturbation during adolescence is a normal means of releasing impulses, and as long as the degree of control is good, there is generally no harm to the body. Secondly, this period of time, men are still children, self-control is weak, easy to excessive, and because of the psychological guilt and fear easily cause serious psychological burden, causing dizziness and tinnitus, memory loss, anxiety, and even make the nerve reflexes less sensitive. Second: the newlywed period Clinically often encountered because of the failure of sex on the wedding night and lead to a year or years of erectile dysfunction (ED) of men, the cause is mostly psychogenic, if men are therefore carrying a heavy psychological burden, is likely to make it more nervous in the next sex life, into the vicious circle of “the more afraid not”. The more you fear, the less you can do. To overcome these problems, on the one hand, men need to be more relaxed into sex; on the other hand, wives also need to understand their husbands. At the same time, before the wedding night, the couple should learn together some knowledge of sex life, to overcome each other’s anxiety, effectively improve the quality of sex life. Third: the wife’s pregnancy and the child was just born from the wife’s pregnancy to two or three years after the birth of the child, parents do have to spend more time and energy on the child, but therefore reduce and inhibit the male sexual needs but it is not necessary. Women are relatively safe in the middle trimester and can have sex as long as they are hygienic and non-violent. Also, women can resume a normal sex life 42 days after the birth of a child.
