When I was a kid, some other kid told me he had a really

neat way of jacking off.  He would catch a fly, remove its wings, get himself hard, sit in a tub of warm water, and place the fly on the tip of his penis with the water surronding the shaft forcing the fly to walk around the head of his penis... that exquisit feeling would cause him to ejaculate.

and no, I never tried....  to much afraid of catching a germ from the fly.... germaphobia.
