I, for one, do NOT want to know about my 18 year old son's sexual fantasies, exploits, or endeavors, any more than I would want to know about my parents. Ewwww! Ewwwww!
You can still be a daily submissive soul to your partner without outing yourself. My Husband tells me what he wants, and I am his caring little wife, who does as he asks. Since you are in a small southern town, this sort of behavior should be no shock to anyone around you. And as you grow older, and show more of your mature/responsible side, most will treat you more as an adult...and those who are still nosey will have to be told what they can do with those noses!
