It is recommended to wait until after the postpartum checkup to resume sexual activity. After that, it is important to use contraception to prevent another pregnancy. It is also important to communicate with your partner about any discomfort or pain during sex and to take things slow. It is normal to experience vaginal dryness and discomfort during sex postpartum, so using a water-based lubricant can help. Additionally, doing active dynamic pelvic floor training can help strengthen the pelvic floor muscles and improve sexual function postpartum.
