Newton...you upset Dravyk so much he can't spell "nauseous." That's *bad.* Quit helping these damned threads!
Anthony...probably because you apply sufficient shaving cream, own a good razor and are careful. Just a guess, as I have no firsthand knowledge with regards to testicle shaving, one - because I personally don't have any; and two - my husband would projectile vomit at the very suggestion. This, by the way, is one of the big benefits of a 26 year marriage. Total acceptance of whatever the other person is just as he/she is. (Marital goodies mentioned for the groom-to-be.)
