Generally men exhibit stronger body hair with higher testosterone but how much so is a genetic component.
Just like women shave their legs male models are often called to shave their chests. A guy at my gym back in the days used to model for underwear and he had to shave his chest because the body image being presented by the media is supposed to be clean.
Hair is messy, curly and above all scary.
This is something that really isn't apparent until you see it in person yourself but a hairy naked dude exhibits a predator response.
From afar the contrasting nature of dark hair on pale skin and its placement accentuate features and transform the silhouette.
I remember having that epiphany when I saw a buddy come out the water at the beach once. I knew it was him but my body was sounding the alarm.
He looked like a buff skeleton and I was pumping adrenaline for fight or flight even though he was a pretty skinny guy.
We all wear clothes today but evolutionarily speaking all these developments are tribal and pretribal genetic selections so before tools and clothing.
Part of bodyhair is quite literally an intimidation.
If that intimidation evolved from the gruesome nature of early human encounters with one another or was selectively bred for in some parts of the world we would have to sspeculate.
Today its a holdover but in days gone by it was like a gorilla developing a silverback when testosterone levels increase enough.
Its just a naked dude but to your reptile brain you are staring at an apex predator that may not be able to afford to let you live to fight another day.
