If voyeurism becomes a persons only sexual outlet it becomes aproblem. If your voyeurism infringes on the privacy of others (ie- peeping Tom) it becomes a big problem.
If you enjoy, and are turned on by watching people in sexual situations, I think you are in the vast majority.
Watching porn, or a sneak peek at some people getting frisky on the beach is fun, sometimes allows us to live out a fantasy we are unable to fulfill in our RW lives.
I love watching people's sex lives, and fetishes. I'm lucky that I can whenever I wish, because my club is a voyeurs paradise. Everything at the club is in full view-the BDSM area, the playrooms, the swing, and the sybian are all out there in full view.
As a bisexual, I enjoy all aspects of Sexuality.
Things I love to watch-
Men or women with anal toys. Specially if they are trying to expand their own limits.
Men fucking. Specially bareback.
I have my own special fetish, and it hurts no one. I love women on their periods. Watching/helping with sanitary supplies, and smelling, feeling, eating, a pussy on it's monthly. I can watch a bleeding pussy all day.
Men's and women's faces in the throws of orgasm.
Enjoy, and stay out of the bushes.
