My girl asked me if I ever masturbated while we were in a relationship. She said she's be offended if I looked at/thought of anyone else while doing it, I said I think of her if I ever have to do it because that's the truth.
I won't reveal my girls personal habits but I'll say that most girls have either masturbated or thought about doing it. I don't see what the big deal is to be perfectly honest.
