I also agree that you just have a fetish for **** sex and are not gay, but you might want to think about if you like the idea because you are submissive, or like to bottom instead of top. If that is the case, I would suggest looking for more dominant women that want a submissive partner. She would also most likely be more open to things like strap-ons and penetrating you.
I hope you find the woman (or man if things change) that you're looking for~
