pelvic pain with orgasm

[charlyruckus.livejournal.com]

What would cause minor left-sided pelvic pain after orgasm?

For the past couple of months, I have been experiencing a very minor yet quite uncomfortable feeling that begins moments after orgasm and lasts for approximately 2-3 hours. It feels as if the pain (if you could call it pain) radiates from behind the left side of my pubic bone, at my mons.

I have been to the gynecologist about it, have received ultrasounds, had a pap smear and an internal exam, and I appear to be completely fine. The pain, however, is still there. It's more annoying than anything.

I only ever engage in non-penetrative sex with my girlfriend (I don't like having anything inside my vagina), and I masturbate via clitoral stimulation. Whatever the pain is is strictly caused by the act of having the orgasm.

I've had no other symptoms and before a few months ago, I've never experienced this before in my life.

Thanks.
