Been 3 days since i've had sex. the bones in my lower pubic area are still very sore plus the clitoral area. what causes it and how do i help the pain?

Coital trauma: Not to be rude but it sounds like you & your partner might have been overenthusiastic 3 days ago, leading to soreness. You can try to OTC pain medications if it bothers you that much. Ice or cold compresses are typically recommended for injuries (warmth for infection). And plenty of time & rest. In future, consider taking charge of fun times to minimize risk of injury. If pain persists, go see doc
