Ouch :(

Husband and I were getting dirty last night. I got on top of him to ride, there was this horrible pain when he was all the was in, to the point we had to switch positions. He was on top and the pain was still there every time he thrusted deep. Afterwards, the pain continued, just not as strong, for the next couple hours. It felt similar to the worst period cramps you could imagine.

Anyone have any ideas as to what could have caused this? I've never had this issue before and now I'm almost scared to have sex again!

Thanks for any and all advice!
