In other words, I, Sherman, a heterosexual lifelong basketball player, have seen a lot more cock and man-ass than many gay men.
As I age, my cock is essentially the same one I owned in 1983. But my balls and ass are loosening and threatening to avalanche down my body. I think I'm an attractive man wearing clothes, but when I'm naked... well, let's just say that I'm grateful I have a pleasant face. And, grading on a curve, I'm actually a relatively fit middle-aged man. All around me in the health clubs, I encounter mountainous guts that make my chubby belly look like a foothill. I see butt cheeks that look like two Sasquatches playing tennis. I recoil from feet so gnarled, hirsute, and abused that a hobbit would suggest a pedicure.
So why do certain homely straight men worry that gay men are even remotely interested in sexually harassing their concave asses? If strange women don't amass in large numbers to jump your bones, then why would packs of gay men hunger for you?
And, hey, I don't mean to punish those folks who are not hot, hot, hot. The plain and the lovely deserve equal amounts of love. I am only talking about sexual objectification.
