Rofl. Come on. Why are we being so obtuse.
Look, it's fine to have sexual thoughts about women in revealing clothing. Or vice versa. Much of that is pretty innate, especially when you're in high school.
Well adjusted people know that ACTING on those thoughts is rarely a good thing to do. When people say 'don't sexualize' they often mean: 'don't act inappropriately.' This shouldn't be hard for people with any self-control.
Shocking this is a debate. Or can some people not resist harassing women at the swimming pool?
