I'm one of the few people I know that has never cheated on a partner. I've been cheated on...and well.. it's not a good feeling. Which is the main reason why I wouldn't do it. Have I considered it? Not seriously...sometimes you see a girl and think wow... hot, but that's pretty much the end of the line.

Here's some good advice;

Don't ruin a good thing by cheating...and if it's not a good thing... break it off before someone gets hurt.
