thingsteal: Last night I hit my wife's cervix and we had to stop because it really hurt her. It's been a long time since I've done that. Usually I'm very careful. I've been told it's probably similar to a man getting kicked in the nuts. It always ends sex. We were doing it from behind. If she's lying flat on her stomach on the bed we're OK, but she likes to get into it and arch her back up and get on her knees for a true doggy-style. I just went too far in the wrong direction. I still had at a good 2 inches "in the cold", so it wasn't like I was shoving the whole thing in there or being rough. She was cool about it. Next time we'll just be a little more careful.
