A long fat stick
They are just being perverts and they like talking about that even though they shouldn't.
ABSOLUTELY!!
they have a penis and testicles.
video games are very attractive to young boys. Little brothers, especially. Boys are obsessed with video games because certain video games have things that boys really like. Such as Mario Kart, little boys whom like that game are interested in cart racing. Boys whom like games such as Black Ops are interested in war or guns. Each video game matches a boy's interest.
you mean like private parts? vagina
The difference is by just looking at the private parts or bladder. By just looking at them you will know that a girl has a vagina (which looks like a hole) and a boy has a penis (which is a bit like a stick)
it turns them on ;)
nothing but video games and recess!
looks bad
Because they like it.
Dogs clean their private parts because it's actually like giving themselves a bath, and it's a lot easier for them.
