I am not an authority on this subject, but I can vouch for this.
First my lover who i service regularly, that's it, I deepthroat him.
He has a hairy chest, and arms and uncut cock 9 1/2x 6 1/2.
Then I met a big man about 6'3 and 260 at a Burger king, fat fingers, with a wedding ring, big feet.
When I was about to leave, he invited me to his tractor trailer cab , parked behind Hannafords Grocery store.
In any case when I climbed in on the passenger side,, he was lying naked, a beautiful hairy chest i must say.
Hung average about 6 inches soft, but he grew and grew to 10inches and at least 7 inches around.
I got it all but it took some time and then he also came more than I ever had a man cum.
it may sound crazy, but at least a half of a cup.
So hairy men don't all have small penise, neither do smooth men all have large penises.
But one thing I can say, sometimes short men will surprise you with a whopper.
10x7 is the biggest i have deepthroated to the nuts and it was hanging between a man with a very hairy chest.
