Sex is not recommended 1-2 days before or 1-2 days after the end of a woman’s period. Because if menstruation is about to come, the hormone level in the body has begun to change significantly, the endometrium has entered the secretion phase, the woman’s libido will be significantly lower, the vaginal secretion will be significantly reduced, and the quality of sex at this time will also decline. The quality of sex at this time will also decline. Moreover, at this time, because the endometrium is about to fall off, it is easy to cause the endometrium to fall off early due to sex, which means that it will cause the early arrival of menstruation. At the end of menstruation, the endometrium is not very stable, if you have sex, it is easy to cause menstruation, so generally in the period before or after the end of 1-2 days, it is best not to have sex.
