Hmm if there is a rawness you are feeling...only thing I can think of is that there is not enough natural lubrication (that is if it is a rawness of your penis). Where does the rawness occur?

You also mention you feel like a rag doll when she is on top, perhaps she is too vigorous, maybe have her try it nice and slow at first, then as you get used to it, slowly speed up and see if that helps.
