Voyeurism isn’t something that’s talked about for the most part, but without those exhibitionists, what would voyeurs do? Having sex in a public setting isn’t just for those who want that extra added thrill of possibly getting caught. People having sex in public must know there is the very real possibility that voyeurs are around and paying attention.
Perhaps that’s why there’s at least one voyeuristic scene in most porn movies. Voyeurism is titillation in more than one way. It’s not just the people being spied upon who are aroused by the actions involved. Frequently, however, those being spied on don’t know they’re being watched. That’s the thrill for the voyeur.
Personally? Don’t know that I would have sex in public – participating in a scene in a private club is one thing, having sex in public or in front of a group of people is entirely another. Voyeurism? The idea of that doesn’t bother me as much.
