Only with my finger, not with a strappie or dildo. Most straight guys aren't into it.
I've shoved fingers up a guys ass, but never used a strap-on on a guy, only with a female.
Met a lady a year ago who was very much into it. Her idea of great sex was having a pair of bi males to take in turn with her 8" strap on. She could orgasm using it on them. She'd also use it on herself as the mood took her. Often while watching the men go at each other.
Nope. The only fake doodle I'm gonna be using is the one on myself.
I have zero interest in being pegged.
