I have no problem with it and I think that envy you feel is extremely common in men even if they dont like to talk about it.
Just last night I was watching Dirty Dancing with the wife and the scene where Patrick Swazye is dancing shirtless and about to hook up came on, I remarked out loud that the fact that guys that good looking exist is extraordinarily unfair to guys like me. Because how am I supposed to compare to that?
And yeah I am a little jealous of a guy that is physically impressive and wish I had better muscle definition, thicker hair, taller and less belly fat.
If you don’t think it is common then why does Mens Health magazine publish shirtless Adonis on every cover?
