I was raised in Oklahoma, my teen years being in the '70's and '80's. The sexual atmosphere then wasn't so much repressive as it was just plain ignorant.
Fortunately, I hooked up with a much older Okinawan woman while I was stationed there. She was into Shibari, Tantra, and BDSM; and I was the perfect blank slate for her to train. Good times!
Because of this, I don't spend a lot of time agonizing over my sexual tastes, nor do I try to catagorize them. They hold about as much importance to me as my preference in foods. For instance: while I like all kinds of cuisines, the fact that Mexican is my absolute favorite doesn't keep me up at night.
In fact, just about the only time I think about it is when I'm dealing with other people's mindsets (good and bad).
Here's the bottom line for me in ANY activity: DO NO HARM. The only time I question my actions is when I'm making someone else miserable. At 41, I've got more than enough bad karma; don't really need any more.
