I couldn't help but notice that OP only left negative options and "other." Does "sleep around" mean cheat or does it simply mean "get all ya can" or "get a lot?"
There are lots of interesting people, and interesting characters, who get a lot of play. In fact, there are tons of interesting people/fictional characters, who cheat on their significant other/spouse who are interesting. From fiction: the title character of Nurse Jackie, the second-best series on Showtime at the moment, is having an affair with a co-worker. She's also a pill-head, a brilliant nurse, and a (somehow) wonderful person. The character is compelling because of the dichotomy - she's both good and virtuous and deplorable and selfish. Kind of like...um...real people.
It's only one aspect of a person's life. Should people look down on former President Clinton because he couldn't keep his hands off the chubby girl and cheated on his wife? Sure, to the extent that it's any of our business (which it is not). I'm certainly for condemning cheating in general. But going after individuals who do it when it doesn't impact your own life is treading far beyond the borders of your own beeswax, and Imma tell your mamma that you're a tattletale.
OP sounds a bit like a Christian Right moralist. Truthfully, I don't spend a lot of time thinking about cheaters or others who have a lot of notches in their belts. My state senate tried to pass a bill making it a felony to officiate at a gay ceremony while putting 2 thirds of our retirement home residents out on the streets and laying off a number of our teachers. Our government is also renting out a mansion on our dime while his home is being remodeled. Wanna guess which state I live in?
Didn't mean to be impertinent there. The point is, unless you cheat on someone I care about, it isn't my business.
