Objectification is natural in a species that reproduces via sexual reproduction.
The key is sexually objectifying (recognising an attraction) whilst respecting said individual.
As a gay dude I see _plenty_, _pleeeeeenty_ of women wantonly objectifying men when they choose to, with no repercussions or qualms. It's just unfortunate because of sexual dimorphism and expected behaviours, men are expected to take the more active role most of the time and hence these reprehensible behaviours are more common amongst men.
Would be really fun to be a god and tweak everyone's brains such that heterosexual men take the passive role just to see what happens.
If we're going down this route I feel you should think about how likely it would have been that I got a similar response if I called out the objectification of men.
