I would mention this to your doc, pain after sex or orgasm shouldn't hurt. There could be something gynae going on like endometriosis or Pelvic Inflamm Disease, or a cyst on an ovary.
I had these symptoms too, and during ovulation and menses!
I was covered in endos all over my bowels and bladder, they're like barnacles on a boat!
so get a referral to gynae, get it checked
You can read about endometriosis in the ForumWiki
hope you're ok
