All I can say is A LOT of us guys just can't leave it alone! and we learn to "experience" it at an early age! For example ~
Last year Angie came home, from teaching her 6th grade class, just busting up. I guess a group of 6th graders were in the middle of the school yard, in a circle, "sizing" up

. Usually it's the
BIG guys that start it!
Around our house with me, my son, my nephew, brothers and brother in law hanging out...someone always has their hands down their pants. Angie is always yelling at us "Just ONCE I want to see ALL of your hands!!"
I remember staying home from school in 6th grade..."cough-cough"

to sneak peeks at dad's Playboys. He worked all day and mom worked the school cafeteria cash register...had a "free" 3 hours!
My friend got called to his son's principal a few years ago, seems his 5th grader got caught with dad's Playboy...but blamed it on another boy...who's parents showed up too! Was he ever embarassed!
When my son was about 3 and a half he went with me to check on a job. Now the street we had to go on is wide and a little hilly, we used to "race" up and down it from time to time when we were younger 'cause you could get a little air-borne without going to fast. Well, I was taking it safe...but a little quick...hit the one rise in the road where the bottom drops out, my son says to me "Whoa daddy, my weiner popped out!" I just smiled and said "Mine too." My son is almost 26 now, when I tell the story he just says that the hill still does it to him!
I guess the point I am trying to make is to us guys it's normal...and you gals just wouldn't understand!
BUT ~ I think the teacher NOT making a big deal about it was a good thing ~ BUT, I think she should have told the parents right away!
