My wife pegs and dominants me, first and only girl I've ever been dominated by. It's legitimately a lot of fun, but holy fuck is it painful if you're not prepared for it.
I don't consider myself gay, because I don't have any attraction to men. The strap on is just a tool to reach a new sensation. If a man wanted inside me I would very much not be into it. And like others have stated, I don’t believe there’s anything that a man and a woman can do together that’s homosexual.
But you know, consenting adults, and all that. What people do in their bedroom I literally don’t care about as long as no one‘s being hurt...well, unless they begged for it first.
