It's not the size it's the position and how deep. For instance: my guy is about a good 6-7 inches hard, not too thick, but good enough. He loves this position where I'm on my back and my legs are in the air and he uses my legs to lift me up off of the bed. The shit hurts so bad and makes me feel like I have to pee pee. And I tell him to stop every time, but he always tries it....some men enjoy painful sex. somewhere along the line they got it in their head that if she says ouch he's doing it right....but sex should not hurt so much that it makes her want to stop.
I don't think its about trying to cause you pain. That position is pleasurable to some women. I think it must be the angle It just doesn't work for you. It will however cause some women to squirt. But I've had women to orgasm like crazy from that position. It helps stimulate the G-spot.
