At first, I thought it was rooted in the attempt to be validated or accepted because gay folks used to portray an image of inferiority and being undesirable. So if you look fit and perfectly attractive in the eyes, you can be seen differently. Reduce a human to a bundle of atoms and nothing more, then you cannot help but treasure only his or her looks. However, I guess, this was twisted into an entirely different notion and now gay men have overlooked the purpose and got more focused on looking attractive to be accepted. I have seen this with some gay people I know – they literally grade people, men or women, on how fit they are.
