Sorry, I do not know exactly where sent the answer... but I repeat:
I don't know gays who hate their bodies, I know gays who enjoy their body more than I do with mine, being heterosexual. You may refer to transsexuals, mental sex with a different body, then it is understandable that they hate their bodies.
I understand that the article refers to obsession to have a perfect body, but that is not exclusive to gays, I'm heterosexual and I'm also pretty obsessed with keeping my body fairly well, and many people like me, not only of my environment, gays included. From my point of view are the times, we want to be beautiful, want to look and be healthy. While there is no radical obsession...
