Huh. How old, exactly, does a person have to be before it's "gross" for them to have any interest in sex?

I agree that unwanted attention can be a problem, but I'm not really clear as to why that is dependent on age. The most obnoxious attention I've ever gotten (you know, back when I was still young enough to have sex, or for other people to want to have sex with me) has always been from guys in their 20s.
