It can be fun at "bikini time". I doubt I've ever know a woman (or girl, when I was a teen) that didn't trim the hedge at least a bit, and if it's someone you know intimately, they can get kind of a rush when you give them an assist using the old beard trimmer. "What number do you want it set on? Same as my goat? Then a "2" it is! Yeah - it really does tingle, doesn't it."
