I dunno about the whole sex with guy thing...I'm a lesbian after all.
Katie - like you I hear that the guys can't take it to the limit and get the girl off with pure penetration...usually have to warm her up with oral and fingers first.
Emotion - girl...if you can get yourself there teach your BF to do it too. It's quite easy for a partner to do it once they've received instructions. Try masturbating in front of him...he can take mental notes and get the hint as to what you like.
Haz - Seriously, if you're left not satisfied and frustrated then you might as well write out instructions on how to do it. I like to call it: Getting Me Off for Dummies or the Untalented.
