Advice

So, I love my gf and the female figure. However I constantly feel the urge to get man handled from behind by either her with a strap o. Or sometimes I think about a guy doing it. But the thought of a guy over me(no offense) doesn't really get me as excited as her dominating me( though I get really excited). I guess what I'm asking is, do I just need to explore or am I a just a confused gentleman with a pegging fetish?!?
