I think it provides a vehicle that makes it easier for one who wants to stray, to stray. Kind of like, I drink more Starbucks now that I found one with a drive thru. I don't have to drag two little kids into the coffee house, so yay me! I can do it with less of a hassle...
Weird analogy, maybe, but you get the idea. Someone who is thinking about messing around has now got an easier place to look for those old boyfriends/girlfriends they used to wonder about. Or, a place to chat with cute co-worker after hours without actually getting together or calling from home.
I saw something online about Craiglist personal ads and some services being blocked for basically being prostitution. So I went over and checked it out. Not to use, gross!!!, but to see what they were talking about. Do you know how many married people had posted, "My wife/husband doesn't like to have sex, I just want a no strings attached hookup partner", etc, etc
It's like they don't even have to bother going to the bar anymore. Just sit on my couch, type up a post and wait to see if any fish will bite.
Again, it doesn't make a faithful person stray, but it makes it easier for one with a wandering eye to do what they are thinking of doing.
