whats the spiderman position? 
Spider-Man can either be performed right side up or upside down.
Look at a empty corner, now position one leg up and one leg down use you hands as stabilizers. If you get good enough you can actually walk up the wall. Now, once you get better, you can screw a petite chick in that position. But your legs and arms must be able to hold he extra weight. And it works best if she has her legs around your waist...
It can freak them out if you are half way up the wall.
Upside down is kinda like you are doing pushups, but your legs are up in the wall corner. And you still have the woman's legs around your waist. By varying the angle of the "pushup", you are varying the angle of the position.
This is a great exercise, as the tris get good pump, and you canalso do a side to side motion as well.
