Do men really cheat at their bachelor parties?

I'm about to get married and there's been some talk of my fiance's bachelor party being in Vegas for 2 nights.. I'm super uneasy about it. I've been doing some online research.. polls and stuff and what I've found seems to say that yes, its a 50/50 chance of a man cheating with a stripper/hooker.. due to peer pressure, alcohol, etc. I trust my fiance, but I don't trust his friends. They keep making comments like "It's your last night as a single man" and that makes me nervous... because he's NOT single... we've been exclusively dating for 8 years! Help! Do men really cheat at their Bachelor parties, or is it more an urban myth?
