Lol. Friction during intercourse mostly, if we're talking pubes, though also w/ inner thigh generally. Armpit hair alleviates friction too. Head hair is just for sun protection really.
HAW !
That i never heard before.
So not true.
I am pretty sure that hair when wet will cause irritation of the skin when rubbed constantly.
Most endurance sporting people are either trimmed or completely bald.

It is probably there because men and women share dna. Perhaps because a thick bush protects a womans vagina from insects.
Perhaps mostly when a woman is pregnant.
For a man it does not do much other then just being there because of men and women similarities.
Men also have nipples which are of no use.
It is just because we evolve as we go.
But to be sure, we will have to go back hundreds of thousands of years when men and women did not wear clothing and only lived near the edge of forests and close to sea water.
There is no intelligent design. Some things are just redundant because there was no evolutionary pressure.
