After 42 days of normal delivery, if the external genitalia are completely restored to normal, you can have normal sexual life. During normal delivery, the cervix and vagina will be damaged by dilation, the cervix will become one-shaped, the folds of the vaginal wall will be gradually flattened, and there will be malodex after delivery. It takes about 42 days for the reproductive organs to recover after delivery, so you cannot have intercourse during this period, otherwise it will easily cause intrauterine infection or affect the recovery of the uterine lining. Under normal circumstances, you can have normal sexual life after 42 days after delivery, but you should avoid excessive force during the first sexual life after delivery to prevent the vaginal mucous membrane from laceration. Some mothers may experience local pain and discomfort due to lateral incision wound or injury, so it is necessary to postpone the time of intercourse. In addition, since ovulation usually resumes 3-6 months after delivery, and it is difficult to detect pregnancy during breastfeeding, abortion is more damaging to the body at this time, so contraceptive measures should be done during intercourse, and an intrauterine device should be placed 3 months after normal delivery to avoid another pregnancy.
