Cheat and tell?

depends how long you been with your partner.. but in honest truth I would keep that to myself...

Well that is something to wonder over. It would depend on if you would have to worry about this person telling your current partner. If not, then I suppose you could be quiet but if he were to find out, he would rather you be honest and apologize (if your serious) about it and explain how and why. I'm sure he would appreciate it a lot more than hearing it from someone else.

Yes, I think you should and I think your partner has the right to know. As hard as it may or may not be, the longer you wait, the more it will hurt for them to find out and they will feel as if you don't trust them anymore. If you explain what happened (most importantly that you were drunk and all your did was make out) and if they truly love you, they will be hurt at first but understand and get over it. Although don't treat the situation as if it was no big deal because they may feel very hurt and treat it as a big deal. If you are truly sorry, they will know.
Tell them (:

Goodluck and hope this helps! (:

Sounds like you and he have a lot to talk about either way.

I would not. And I would start wondering about my drinking habits!
