Query: Don't buy unless you're into guy on guy, or orgies.

The description sounded ok, but when I got the book and my girlfriend and I started looking through it... uh, yeah...There are girl on girl, guy on guy, two guys on one girl, etc... (none of which is going on in our house, or ever will). The rest of the positions are pretty average and nothing too interesting. There are a few, but not worth looking at drawings of three dudes all plugged into each other like game of leap frog gone terribly wrong. If I had known that I wouldn't have bought it. Save your money, try a different book, unless your horizons are that broad, then go for it.
