I have sex with my boyfriend a few times a week and once every couple of weeks I'll get this super uncomfortable burning pain about 2 minutes after sex. We don't use condoms, so it's not a latex allergy. He sometimes pulls out, sometimes doesn't, but I haven't kept track enough to know if it's a pattern with my pain. The pain starts when I pee immediately after sex, almost brings me to tears. I put a wet cool wash rag and pop a couple of ibuprofen and the pain goes away within 30 minutes. Then I could have sex the next day and be totally fine and pain free. I've been tested for STD's and UTI's...not sure if this is just a random occurrence or something I should worry about. Help!
