I'm changing the name to "ball smasher". I've tried this position, although not as extreme as the visual provided on sexinfo.com. I was more squatting while thrusting downwards. The visual for both parties involved is fantastic, however, too hard of a downward thrust will smash his balls, hence the "ball smasher". My erections are usually very rigid and upright, but this position wasn't a problem.. as someone else said, the angle can be adjusted to be enjoyed.
