Your mirror-world example leaves one important factor out: context. That is, the larger social context is a world of unequal gendered power dynamics. I think your thought experiment is accurate in its depiction of what that flipped situation would look like, but you are implying the difference is in sensitivity or disposition. I think the difference is actually that men can laugh at that stuff because a) it's ironic in that those images are typically the other way around and b) that sort of objectification of the male body isn't reminding them that they're at greater risk for sexual harassment and assault. Because they aren't. The problem is that those images and that humor, in public, about women, happens in the context of a world where women are more easily abused, assaulted and harassed, and men more easily get away with it. So context matters, and in this social context, that "humor" shouldn't be acceptable.
