Except the comic doesn’t show them discussing or showing a naked body, it’s a weirdo pointing out the genitals to another person in a very public place. If it was toes, it’d be fine. If it was just a naked body it’d be whatever, mostly. But they’re specifically pointing out genitals, that implies sexual focus. It’s only “cute” and “funny” for the old women here because eventually it’ll be an organ used for sex…
