Can you have sex before menstruation?
Prior to menstruation, it is generally safe to have sexual intercourse, which usually does not negatively affect the body. The specific analysis is as follows:
During menstruation, the cervix is normally open, and sexual intercourse may allow bacteria to travel upward, potentially causing infection. However, before menstruation begins, the cervix remains closed and there is no vaginal bleeding. Therefore, having sex at this time typically does not enable bacteria to enter through the vagina and cause gynecological infections via ascending spread. Additionally, intercourse before menstruation generally does not cause the period to start earlier or later. Thus, sexual activity is acceptable during this phase, but personal hygiene should be carefully maintained.
If pregnancy is not desired, it is advisable to use effective contraception during intercourse before menstruation to prevent unintended pregnancy.
