Your questions are very allusively written and your pronoun use is informal, so I can't always make out exactly what you are saying. If you have a first language other than English (such as French, consistent with the name Justine), I'd be glad to see how you'd express a couple of your sentences in it, specifically:

"All of our body parts grow, and to deal with the feelings and use of each can lead to what one may call the 'forbidden zone' or private parts" and

"How did the feelings come out of all this playing around with the Forbidden Zone in which one's Private parts came into play?"

If not, I'll comment based on my tentative understanding. But I'll wait to see if you'll give me another version first.
