Generally the uterine cramps would be brought on by Oxytocin (which is something that is released in great amounts prior to and during labour) and also Prostaglandins are the hormones that are necessary around menstruation. Did you ever have pain when you had menstruation? I used to have terrible cramps before I had my babies and it was apparently due to the high levels of prostaglandins. I am not usre though about orgasm, but I do know that the whole uterus contracts during orgasm, so this may be something that caused your uterus to cramp quite severely. if those cramps were anything like labour, then to be honest I think my sex life would have took a nose dive also. Certainly would have knocked the five kids idea on the head anyhow. I'm not really sure about it being related to clitoromegally, but as far as I knew the uterus can be affected in the development area with the androgens in utero due to CAH. Perhaps other's could advise you better here.
