By: Chris Iliades, MD, Everyday Health. Many men stay closed-mouth about their health, be it an illness or weight gain or wacky sexual problem...

"My youngest son wanted to know what the 'part' below his penis was," one mom tells me. "I explained to him that it was his testicles. He quickly replied he didn't like the look of it and could I take them off!"

I don't want my son growing up with embarrassment over something so overly hyped as sex. It's just sex. There are worse things than sharing orgasms (as long as he has a condom) and he should understand that sex is for more than reproduction and doesn't have to be done only with someone you love.
