Cuz it itches.

Because women do not sweat - they "glow". Men, however, sweat like the pigs they are and sweat down there itches so they are always scratching. A guy who does it in front of a girl is gross and certainly not boyfriend material. A husband may do it in front of a wife as they said "I Do" before she said "The He&ll you don't".

Put it this way: it's crude and disgusting. It falls into the same category as guys walking around with their pants hanging off their a@@es!

Oh...they do it because they think it's "cool." The only other reason I can think of is crabs or lack of hygiene which causes them to itch a lot.

because men are wild animals

We do it in private too
