you need to talk to your partner about it since it's the first time you experience it. somehow this comes up from a deep thrusting penetration.

Occasionally, a woman will experience pelvic pain upon deep, thrusting penetration. Many conditions may cause this pain, including:

* tears in the ligaments that support the uterus (causes include problems during childbirth, inappropriately performed abortion, previous violent sexual intercourse or rape)
* cervical, uterine, or tubal infections, such as pelvic inflammatory disease (PID)
* pelvic adhesions (often the result of previous pelvic surgery or PID)
* endometriosis
* ovarian cysts
* uterine fibroid tumors
