People of Reddit: what was the weirdest or most taboo thing you did or encountered in a sexual relationship?

1. Girl asked me to play rape. I thought, seems harmless enough. Her first request was for me to put a nude centerfold on her back. Then she asks me to smack her. I give her a good ass slapping and she says, "no REALLY punch me, like in my ribs or my face... something." Only time in my life where I said, ya know, I don't think I can do that.

2. I had an ex who cried after sex. Not just blinking back tears, I'm talking full out near hyperventilation style uncontrolled bawling. She assured me she had no sex issues and I'm honest enough to admit my skills are average at best so this was just a very weird quirk.

3. Nothing too horribly crazy. Weirdest I guess was my gf and I let a girl at a party we were at masturbate to us while we were having sex. It was hot seeing her get off to us getting off. Now, looking back on it, it's kinda weird thinking about how a girl was in the corner of the room fingering herself while my girlfriend and I were fucking on the bed in the room. In the moment it was pretty hot though.

4. He was into shibari and choking me till I begged him to stop. Not the best top but it was different and exciting.

5. Was making out with some guy from my school (I was 17 or 18 at the time), things got heated, I reached down his pants but didn't feel anything. Legitimately I could not find his dick. He pulls down his pants and my eyes met with what looked like a newborn baby's peepee. I've changed diapers before and this was definitely newborn status. I stared, stuttered, and told him I was ready to go home now. More awkward for him than me, I guess.

6. Mine was while I was stationed in Italy a girl had me donkey punch her. I was a bit taken back by the request by I did as she suggested but it was a very light tap to the back of the head. She turned toward me and said harder so I obliged. But not crazy hard and again she said "harder don't be a bitch". So again I obliged and hit her with a good but of force and she instantly had an orgasm but she also Baaaa'd like a sheep at the same time. I finished even tho I was freaked out got dressed and left.

8. Nothing too crazy. I've had two instances where someone was watching us. The first time creeped me out but the second time was pretty hot. I think it was just the people involved each time that changed the way I experienced it.
