Idea is exciting as a fantasy. Way too risky in real life. As everyone has said what is on the otherside is unknown. If you've already got some STDs or something I guess there's not much to worry about. Personally, I would be so worried about the stuff I could catch that I wouldn't be able to enjoy it. That was one of my favorite Penthouse sets though. If those girls were there, I might have to fight myself away.
