You shared a jpeg of a material a dude created without crediting him. My goal was not to distribute blame but correctly credit the author.
Additionally you might want to check his stuff directly on his website considering it's free and you seem to like what he does.
I would say it would be nice to credit the cartoonist who created that pic instead of just posting the jpg? Sorry if I missed such credit giving.
If I haven't, it's from theoatmeal.com
Is there anything to back up that study? i would have thought gym queens would have been all over that for a while, if it was true 
it's only a fail because it finishes by joining both sides which makes a very long goatee! But honestly I would be more enclined to call that a success
I shaved only once in my life, for a very specific reasons (yeah, crabs). And while it was fun on the spot and yeah my dick looked bigger, there are two downsides for that.
First, as I later learned, shaving is unnecessary to treat crabs (oops). Second, when hair grows back it feels just horrible and scratchy.
Everywhere I look, even in some hairy guys movies, balls are shaved. it seems to be pretty much the norm nowadays. But those are very loose skin, would really freak me out shaving that bit!
Talking from France, with very limited statistics (Based on my brother and I), apparently straight shave more than gay
But yeah personally I don't shave anything, I find it easier and like guys who are natural too. If you look at porn I could get the impression it's far from the norm though. I watch quite a lot of straight porn and the difference there is not in terms of straight more than gay. It just depends on the actor and type of movies.
