I definitely did a lot before I was married...pure boredom was the main reason...and obviously, other parts of the relationship was failing besides the sex. After marriage, I got involved in a relationship but both partners knew about each other, so is that cheating? I love both...would I cheat on them? Probably....

I didn't really cheat but I was enjoying life to it's fullest and I had 2 sexual relationships going at the same time. One guy found out and was upset (they were both just flings, no commitment) I still carry guilt over it and it was over 40 years ago Never did that again.

Yes once when i was 17/18 ish. Gf was on holiday, I got drunk and ended up with someone else. She heard on the grapevine whilst she was still on holiday (no internet or mobiles back then!) and came back pretty upset which had a lasting impression on me. I just consider it part of a learning curve now, it's never been repeated. For somebody stuck in the wrong relationship with no communication I'd struggle to criticise them for doing it though.

Apparently, I didn't know we were exclusively dating. I was informed of this later. I think I was 18 at the time. Ever since then I've made it clear at the beginning of all my relationships. She and I will be having sex with other people together and separately. Haven't cheated since.

No, never.

Absolutely not! Despite being cheated on a few times. I'm bitter, but it's not the next guy's fault.

I was just a kid. I passed Go and collected $500

Yes when I was in my early twenties and I am still ashamed of it. I did it from having low self esteem, when someone else paid me attention I ran with it. I have never forgotten it and I am still disappointed with myself.

No.
