Pounding Too Hard?

I dunno what it would be like w/a guy whose like 10 in. but my bf is about 8 in. and I love when he does it really hard but not right at the beginning. But he does it great where he'll start slower and just build up and when I cum I totally want him to go hard cuz it makes it bigger. I think prob. there is a thing as too hard depending on the woman and the guy and how big and all that, and also like I said I don't think I'd like it super hard right from the start.
 
Ever heard of "uterine prolapse?" I know of a woman who had this happen after a well-hung guy pounded deep and hard. This was many years ago. However, be very careful!!
 
I had a good friend of mine go to the hospital because of SOMETHING going wrong during hard-sex. Can't remember the specifics.

Apparently this is not that uncommon... a nurse I know said it happens regularly. Of course, this is set apart from all those rather unrealistic urban myths where hysterectomies are required after a sailor goes to town.
