Men half a month without sexual needs, most of them are normal, if there is no physical discomfort then there is no need to worry. Men’s need for sexual frequency will gradually decrease with age. In addition, if men recently because of work pressure or encounter a major traumatic event (such as the loss of love, the death of a loved one), can also lead to a decline in sexual desire, no demand. There is also the fact that if a partner is pregnant and is in early pregnancy (first 3 months) or late pregnancy (second 3 months), men will be afraid that having sex at this time will have an impact on the fetus, so they will choose to restrain themselves from making sexual demands on their partner and to divert their attention and lower their sexual desire through other means (such as exercise, masturbation, etc.).
