Forgive me if this has been discussed before. Years ago I read that if you take the middle finger of a man's hand, and bend it forward to touch the palm, as low as it will go, then the length of his erect penis will be the distance between this point and the tip of the middle finger (extended). Well, it works for me, really closely. But on the occasions when an experiment with another guy was possible, we always had some other agenda. Does it work, for you? Is there any correlation between girth of penis and of fingers?
