I did it for the first time recently. I was scared as hell when I started going for the close dry shave...made a mess on the floor as well. I kind of feel like a pornstar now.
Dude why shave your sac when just break out your handy hair trimmer like flowbe or other type and go to town. No razors near your little commando from the land down under and much faster not quite as clean as shaving but looks cleaner for that special someone or for yourself
from my ..........limited experience in this area (size comparison quick sneak peeks in the gym locker room......c'mom now guys, admit it, u do this too!), there is no corelation b/t body hair levels and pubic hair levels.
