It just depends on the man really they are all different. I would have a problem doing hubby with a strap on because I do NOT at all like to feel like I am dominating him. Seriously he put my wrist restraints on once just jacking around and it totally freaked me out. Icky feelings lol. Aside from that he doesn't want anything not a finger a tongue a butt plug nada going towards his exit. I don't know why, could be a psychological thing a physical thing, I don't know and I don't care. It is a limit it is his limit and he by no means has to explain it to me. Who knows people are always changing he was a little shakey with giving it to me anally at first too now he loves it lol.
