ah yes...the age old question "To shave or not to shave??"....I shave...I can't stand body hair.
And the very first time you shave yes it does itch...but past that if you keep up with it, you get used to it. They also have this stuff called Bikini Zone (yes males can use this too) that keeps irritation and itch down. So you don't itch and you don't get the stupid red bumps that seem to come with shaving such a sensitive area.
As for males being completely shaven....at this point I have no preference cuz you sorta gotta be with both (shaved and not shaved) to have a preference...but since I hate body hair...I'd probably like my man to have as little as possible.
