Me and my partner finished having sex for about 30 minutes. After we were done I had a horrible pain in my stomach. It felt like i was having a baby again. has anyone ever felt this type of pain after sex? I have been to the dr and was tested for stds and this is not the case. The pain was so horrible i had to lye down for about an hour; I could barley walk around the house. if anyone knows what was going on please help? Thanks
