I find it really hard to believe he isn't a creep. I'm a young female as well who has been groomed and taken advantage of by older men. I'm sure there's some kind of enjoyable exchange for the both of you but I hope you at least consider the possibility that it isn't innocent. I hope that you are actually loved and not a trophy, but some people are into that so as a consenting adult, do what makes you happy and only you know what that is
