I'm a preacher's son raised with two younger sisters. Sex, and many other things, were not proper topics for discussion. Just about everything about human bodies was "dirty", "naughty", and "sinful".
Of course, that only aroused my curiosity even more!
I remember playing "Doctor", and "I'll show you mine, if you show me yours", as early as 5 or 6!
Heck! Being "naughty" was just TOO much FUN! Even though I had NO idea what I was doing.
I learned about Sex as most kids did in the 1950s and 60s. Through experimentation behind closed doors, in the woods, back alleys, and furtive conversations out of hearing distance from adults.
Since EVERYONE in the towns we lived in knew who I was, and I didn't always know who They were, I had to be Very careful, even Sneaky about it all.
This was also the times of open locker rooms, and gang showers. If I ever let on that my naked mates might be turning me on, I was TOAST! And, Dead Toast at that!
There were SO many conflicting things going on!
Though I was subversively running around naked, dating girls for "the image", and jerking off with my close buds, I didn't actually have Sex until I was in college, 500mi. away from my family's public!
No wonder I'm as warped as I am! HA!
