I'm not for cheating, really, if youre married, you're married. You don't like your spouse, divorce. I don't agree with these kinds of websites, however this one is really out there for actually promoting an affair. However, who's to say affairs don't go on on, say, Plenty of Fish, Myspace, etc? However this is like a big red and yellow neon flashing sign.
Again, I'm not for cheating (who knows what kinda diseases a spouse can bring home, or if they impregnate another/get pregnant) but I would say have this site more for swingers than anything else.
And I don't think it actually causes people to cheat, you have to WANT to cheat to actually seek out a site like this and then hook up with someone to cheat. It's different if you go on actual dating sites to hook up with someone (if you're single) but then remain on the site to hook up with more after.
If I'm not making any sense, sorry, still having my coffee, lol.
