Because sex, like violence, is extremely easy to pervert. But being that most violence is, essentially, a perversion, people don't worry about it as much. Sex on the other hand is often considered sacred, hence the desecration of a thing is logically worse than someone seeing something that's already frowned upon. That's what I figure, anyway. I mean, why is rape like the worst crime imaginable? Why is it so horrible and emotionally scarring? Because it's a perversion of something that, in the right circumstances, should be beautiful and meaningful, not painful and humiliating.
