As you mentioned earlier, this subject is up for debate. I personally have studied human anatomy and am not aware of any true biological way this can be done but I am not an expert. It has never happened to me nor has it happened to any of my close girl friends. But lots of stuff hasn't happened to me and I still believe that it's possible. Heck, I think the fun in challenging the debate is the practice
Keep us posted on your progress...if that isn't too creepy
