Hypothesis: Body dysmorphia for men is only starting to become a serious problem. Wait a generation or so.

“A generation” might be an overestimation. A few hours ago, a Facebook page in Italian about “destroying other people's dreams by exposing the objective truth” published a status “let's tell our gym-going friends that it's cold on Facebook too”, it's been liked by 81 people so far a sizeable fraction of whom are male, someone (using a gender-neutral pseudonym, but with a male cartoon character as profile picture) commented complaining about an “exponential” increase of pictures and videos of people in underwear, and that comment has been liked by 6 people so far of whom 4 males.

EDIT: <troll>I commented “Envy?”, and my profile picture is bare-chested. Let's see how many flames I'll get.</troll> (For all I'm concerned, if you're the kind of person who resents cynicism, you do not subscribe a page about “destroying other people's dreams by exposing the objective truth”.)
