not sure where you get that idea, but I'll fill you in on my grooming.
armpits, chest and stomach - trimmed once a month with clippers
face - shave 2-3 times a week with electric razor
public hair - kept short with weekly grooming
balls - bald
ass, back - trimmed as needed (usually 3-4 times per year)
ass is never shaved bro, there isn't that much hair, and taking a razor to the bunghole is for chicks only.
what do you keep in your fanny pack?
