Sleeping Over

My wife and I were talking with neighboring parents about what happens when your son sleeps over with the neighbor's son. Looking back upon my life, yes we drifted onto sex and wound up masturbating. As long as all parents know this, why the secrecy? I saw the neighbor's kids nude at the community swimming pool locker room their packages appeared virgin or almost virgin. There must be an unwritten code that kids learn about sex from each other rather than parents. At that young tender age, it's easier for the kids to talk about it than for the parent to bring up the subject. If dad brings up the subject, the wife will think he might be a little 'gay in the closet'. This is a no no! As a parent later, I made the statement to my two sons that urine wasn't the only stuff that came out of their peni. The younger of them immediately volunteered that white stuff came out. Enough said!!
