Glossy photos of girls on bikes!

so it makes a difference if people have given their "consent" to be sexually objectified?

but doesn't it come down to feelings? i.e. basically, sexual objectification is: someone thinks "oh they looks nice, that makes me sexually aroused, i'd like to have sex with them", and doesn't everyone, men and women, think that, from an inherent drive to propagate the species? or am i off the mark?

yep, but men tend to place a much higher importance on physical beauty than females do, for reasons probably linked to fertility. this is true across all populations.
