It depends on your definition of "perv".
I'd pretty much try anything not involving animals, children, or acts normally associated with a bathroom.
I'm not into major S&M stuff, but I dig blindfolds and handcuffs. A woman with a whip scares me too much. Especially if I'm naked.

Plus, I'm into making love to a woman's body, not pouring hot wax on it.
Outside of that, I pretty much think about sex, oh, all the time. My libido has changed since I've gotten older. I'm not as wild as I used to be. I only wax the monkey about 4-5 times a week now.
