I must also be blessed with a woman who sincerely likes it. It is very rare that I hint at it that she doesn't do it, and it's quite often that she initiates it. I agree with those that said to handle it by talking to her directly. I find the best way to add something new in the bedroom is to, after some especially good sex, compliment her specifically on what she just did to knock your socks off. Tell her how awesome it was. Then say "you know what else I'd love........if you were ever willing........." and tell her.
