Hairy

Really depends where it is.

Snail/happy trail = extremely hot
Legs, forearms and armpits = pretty much required
Chest = can be very hot, not required, depends on how it fits the man. Anything from smooth to very hairy is hot.
Pubes = hotter with than without, trimmed is the goldilocks style
Upper arms/shoulders/back = big turn off
Bum = light fuzz on the cheeks is hot, smooth cheeks are also hot, prefer no hair on the hole. Very hairy arse is too much.

Body hair is also hotter on a toned or slightly muscular physique, very hairy is not hot on fatter or skinny physiques.
