Grew up in a porn free home. Never got "the talk" but at least dear mom had the grace to leave a copy of "Everything You Ever Wanted to Know.." laying around.

On the other hand, my first porn shoot was at age 6. Christmas morning I got my first camera. A Brownie.
Parents were sure we would be busy with the presents long enough for them to get it on. Back then "Candid Camera" was popular. So I flung open my parents door and pop went the flash bulb. Moms ankles around dad's ears. My very first picture, evah. Somehow, even though I loaded the film into it myself. Turns out there wasn't any film in it later.
