Sexual Intercourse with another person
Yeah, obviously.
Cyber-Sex with another individual
Depends. If you do it because you're bored or for a laugh then no. If you do it because you have some sort of feelings for the other person, then its a mild form of cheating.
Making out with another individual
Yes.
Kissing another individual on the lips momentarily
Yeah in a small way, but I wouldn't get terribly upset over it.
Going to a strip club (Look, but don't touch)
No.
Getting a lap dance
No, but its not something most women are going to be comfortable with. That's one of those gray areas where you haven't exactly cheated but you're probably in some deep **** if she finds out. I wouldn't be that bothered by it, though. I'd just give him some **** for the hell of it.
Hiring a prostitute
Yes.
Phone sex with another individual
Yeah.
Daydreaming/Wetdreaming/Dreaming about having sex with another individual
It's definitely not a good sign, especially if you're dwelling on it.
Picturing someone elses face on your partners face constantly
"Not necessarily cheating but if you have to constantly do that, you shouldn't be in a relationship with said person." - Erz said it best
*********ion
No. Wtf?
Giving a lap dance
Depends on the degree of the lap dance. If the guy (or girl) has their hands all over the other person, then yeah. If its a look-but-don't-touch deal, then no, but your bf/gf/spouse probably won't be happy. I don't really consider it cheating though.
Edit: Damnit, I accidentally voted for that one.
Stripping for someone else
Eh, that kind of depends on the people involved. Some would consider it cheating, some wouldn't. Depends on the circumstances for me.
Also, its really cute that Colossal and Pickles voted for the same things.
