I'm 22 my gf is extremely shy (like me) and I would like to give her a massage (something nice I can do for her that feels good) I have massaged her over her shirt, but never under. I don't want to make it weird, but I would like to give her a proper one with oils under her shirt on her back, etc. How should I ask this? what should I say?? I don't want her to feel awkward or anything.
