This is something that I have always wondered. I can see why we grow hair on our heads and other body parts, but why on our genitals. Anyone know why?
It serves as a form of dry lubrication during the bump and grind. Seriously.
'Cuz it’s cute and attractive.
Seriously, it’s an attention-flag agains the backdrop of our relatively-hairless bodies. Other, hairier mammals may be hairless there, or have other striking visual elements.
The real question is why the heck are so many people shaving it off!
Is it not as a means of spreading pheromones - ie. you get hair where you sweat most (genitals, armpits) which traps your natural smells.
I’m sure I read somewhere (and don’t have time to check now) that the only reason we get BO is because we now clothe ourselves and our bodies haven’t had time to adapt yet (miliseconds in evolutionary terms).
It provides something for the imaginative to shave off.
It looks sexy…or is that just me?
It gives us an excuse to shampoo the area… vigorously.
I wonder how come nobody thought of the obvious explanation: it protects the sensitive unmentionables from the sun, stuff falling from above.
The fact that light cavalry troopers used to braid their hair on the sides to protect the neck against sword blows is quite interesting (this was done even into the times of Napoleon).
Because it itches when I shave it off.
What I was taught in school (and what seems to make the most sense out of all these explanations, including Cecil’s) is that it is, as someone said, an ‘attention flag’.
However, it doesn’t just let others know that we possess genitals, but rather lets them know we have hit puberty and have become sexually active. If pubic hair was necessary to protect the genitals in any way, you’d think it would develop much earlier than puberty.
This seems to me the best explanation for a lot of what goes on at puberty - females’ breasts getting bigger, males’ facial hair developing, etc. Basically, it’s a way to let potential mates know that if there’s no hair ‘down there’, they’re not ready for it.
So we don’t freeze our ****s off.
That’s so I can have some situation in the world when I would choose “bush.”
…well I don’t want to be immodest, but the small amount of overall area that my pubic hair covers isn’t going to stop a lot of sun or ‘stuff falling from above’ from getting to my unmentionables.
YMMV of course 
I always thought it was to floss your teeth with.
slight hijack, but need to know if any other guys like this one.
Shaved. Totally.
I love it, but think others would assume I’m a pedophile.
To the OP, I switch from bushman to bare every few months. Change is good and I get it a number of times each year. FWIW, if you have fuzzy nuts, dry the fuckers before donning the undapants. The moisture has a tendency to put off the one loving enough to have the nose close to the area.
duffer:
On me or my partners?
a) On her: someone on the board has the sig line “If you shaved your kitty cat would you still want to pet it?” Seriously, yuck. It’s hers and she can do what she wants with it, but I’ll find something else to do until it grows back, unless it’s because she’s being irradiated for cancer or something. Little red inflamed bumps, the sensation of running your finger across a rasp file, the prepubescent thing instead of the pretty black wedge-triangle? Yeah that’s real sexy.
b) On me: you gotta be kidding. I’m grudgingly willing to touch up the stragglers on my cheeks and neck in the morning, to make the facial hair I keep (which is most of it) look kempt, but that’s as intimate as I’m going to get with a shaving razor. I had to do this when I got my vasectomy (they handed me a razor kit) and I got razor burn. It looked and felt weird and foreign as hell, and itched like crazy coming back.
