I think what you like changes with who you're with, really. When I was younger I swore the most disgusting thing in the world was a man with back hair, but then I went and fell for a guy who looked like he was wearing a perma-sweater. Next thing you know, I'm no longer bothered.
I do prefer too much hair than not enough on a man. Men who wax their chest creep me right out--chests should have some hair! If a man wants to wax his back, though, I'm fine with that...I just like to make sure I've still got the chest snuggly. :)
I'm not a fan of men shaving their fun zone, either. I always thought it made the testicles looks so sad and lonely. Like wee raisins left out in the cold. Who can be aroused when they're busy wondering if they should knit little caps for the little guys?
(and now we can start the clock for me to eat those words as soon as I fall for a guy who shaves down below...)
