If a couple has plans to have children, it is generally appropriate to arrange intercourse once every 2-3 days. If a couple is planning to get pregnant, it is generally considered appropriate to have intercourse once every 2-3 days as long as the woman has regular menstruation and can have sex normally. If the woman’s menstrual cycle is irregular, or if there is an ovulation abnormality, then she needs to go to the hospital for counseling so that the doctor can give advice on the timing of intercourse. Excessive frequency of intercourse may lead to physical fatigue and weakness, and may also lead to a decline in sperm quality, affecting pregnancy. Less frequent intercourse may also lead to decreased chances of pregnancy. If you are planning to have a baby, you not only need to choose the right time to have intercourse, but also need to take good care of your body, pay more attention to rest, and exercise properly.
