Ok - that is a tough one. If it was in a town where I knew no one and I felt that I could get away with it I just might have a one night stand, provided that the dude was good enough to warrant cheating.

Of course, I would be the one to get all the way to the hotel and get naked and then chicken out because I love my SO to much to waste him away on something like a barfly!

I wouldn't recommend sex, drugs or insanity for everyone, but they've always worked for me.
