My parents never gave me the sex talk, they just ordered Cinamax when I was a kid.  Everything turned out pretty well with me, so I have to assume that's the way to do it.  But if you want to talk about sex with your kids, check out what these doctors and experts from the 60's have to say.

Doctors smoked cigarettes in the maternity ward in the 1960's.

So it's important you listen to what they say and apply it to your life. My favorite quote is at 3:04.
