a start

When I was a kid (4 year old), my neighbor (about 6) had a mom who - I've been told later - was a bit exhibitionist. He basically initiated me to that with a few neighbor girls down the street.
You know dropping our pants and watching each other.
But what really was a strange experiment at the time, turned to be a kicker for a repeat: One day, we were about 6 or 7 kids playing at those girls house when my neighbor (1 year older) told me that they will play cowboy indians and I will be tied up. Once tied up, he told me to drop my pants in front of all those folks. There was about 3 girls and 3 boys. I looked at them looking at my dick, was a bit embarrassed but not that much - was too young.
Now, I think today is sort of a repeat of this event that his playing. But I'm glad it was with kids of my age as today, I'm only interested with this with people of my age roughly (translation: adults)

Now you know why... a start
