Regarding wolf-whistles and such, it seems like in an ideal world, we'd invent a new obvious signal, like a red bracelet or something, that explicitly showed that a woman enjoyed this sort attention.

If some women set themselves apart in this way with an unambiguous signal, I think they'd attract negative attention from people who disapprove of their attitudes.

It's possible they'd be at increased risk from sexually predatory men, but I think it's even more likely they'd be stigmatized by other women who take it upon themselves to enforce social norms.
