Guys: is this considered cheating? iin?

Even if you think it's hot, it is still cheating. Especially if she didn't invite you.

yeah?.....

Yes cheating. Broke up with two girls because the hooked up with girls at partys. After that I never dated a bi girl again. Lesbo sex is for singles. Not couples. Unless you want her to. Would you consider it cheating if you had sex with another guy?

I've told my girlfriend a few times I think it's hot when girls make out and what not. I've also told her I kinda want to kiss a girl,as long as I can see. ;P

Her and her friend (who also has a boyfriend) made out when they were drunk and I watched and loved it! Her boyfriend didn't wanna see, and walked away but wasn't overly bothered.

I don't think it counts as cheating in this instance as the other partners were present, knew it was going to happen and didn't mind it happening. If they'd done it behind our backs, I'd consider it cheating.

I wish it wasn't. lol. But my partner would probably dump me if I did that. Besides, I wouldn't want him to be suckin' dicks.

Is it because it's a girl? You shouldn't react any differently because it was another woman

Depends what they and their partner have arranged. For the most part yes that's cheating, unless the girls partner has specifically said "I don't mind you kissing other girls" and he wasn't joking

Not even if they rub their poons together.
