If I spit at all, I am totally unaware of my doing so and I do not think that I do.

sorta like asking why do girls paint their nails? answer : social convention. you wouldn't be seen dead spitting in the street as we wouldn't be seen dead with pink finger nails . social convention

When I was a kid we used to try to hit trees and other things to see who could do it the best, "hocking a lunger'.

"I really HAVE to know"

oral fixation?

Stupidity makes them do it and that's the only excuse. I'm a guy but there's no way in heck that I'll do it.

I grew up in the south east, and chewing tobacco (around horse enthusiests) was popular in the eighties, more so than today at least. Otherwise, I never got it either.

It goes along with adjusting our dicks through the pants. Grab, spit, cuss. Whoooeee we're having fun now.
My son looked at me strange when he first saw me do it. Then tried himself. Something about ejecting projectile anything at will fascinated him.

Some men do it, and do it for exactly the same reasons some women do it.

All I can say is don't go to China... Everybody does it, no one bats an eye.

Spit or swallow? I swallow, but then I'm not in the habit of "pleasuring" men!!!

When my gf and I kiss, we enjoy passing the luggies back and forth between our mouths.

Umm... maybe you're hanging out with the wrong guys? Maybe it's a kid thing, but I'm 34 and have spat in the street maybe 20 times in my whole life...

I think young boys start imitating baseball players that chew tobacco and then it becomes a habit.

They also seem to love to spit in urinals. Not sure what that is either. Maybe they are so full of liquid they feel it has to come out both ends.

I have never been into sports so the only time I have the urge to spit is if someone sneaks pineapple on to a pizza. LoL
