I vote for none of the above and I can't believe I'm the first to mention this: I hate positions that no one at all would use, and the only reason that the porn stars are doing it is to show the penetration to the camera. I saw a jpg once (i didn't d/l it) where the girl is on all fours, and the guy is kinda fucking her doggie-style. Get this, both his legs were on one side of the girls ass, with his feet pointing away. Call it a half doggie/half squat fuck. Other that being totally fucking amazed that this was possible, and that the guy lived to fuck again, I see utterly no sex appeal in this.
Just show normal positions and my imagination will make up whatever else I need.
