Believe it or not, there is a "museum of sex" in New York (and if you think that is believable ponder that I found it on a medical sources link list for students...) and they have a
Virtual Exhibition which combines my love of ludicrous patents with guess what. "Guess What" is pretty damn obvious, but, I have never in my life been so glad I do not possess a penis. There are scary devices to prevent wet dreams in there.
