Are you providers turned off by hairy man who have hair on their backs and butts?

Not at all! Love the hair. - it's natural and radiates raw primal masculinity. It means you are alive, wild and real.
Don't let capitalism shame your hairy ass just to sell you fancier grooming products

While I can't speak much for back and butt, I've only ever had ladies say they like my chest hair. One that I saw a few times liked to snuggle up to me and stroke my chest and comment on how soft it is after we finished.

..so a feast of pheromones with mutual body hair appreciation is always a pleasure. My unshaven armpits are the perfect spot for a cum shot!
