This sounds perfect in theory but how many of you guys want to hear that you need to "up your game" from a woman? You tell him what you want and his ego is bruised and backs off cause he thinks he's the bomb!
So, tell me how you a woman can tell a man that he is not satisfying her in bed without him feeling like crap?
"You know what I'd really like...." is a good start.
It works with me all the time. For most men...just the fact that the woman is interested is very attractive.
