Arrogance. Some ARE good in bed, but they have taken the opportunity to learn. But too many think that just because the're good looking a man will be so grateful that it doesn't matter if they suck in the sack.
I may be wrong , but I think it's the men that assume beautiful girls are naturally good in bed, guess simply because they do look good :)
It's good to be back !

They may've had the experience of being treated like a pretty toy to play with---nothing interactive expected of them. Some guys seem to have fun playing with the body and forget it belongs to a live person.
Why are we generalizing so much today?
