There are also different kinds of gay men and not just your stereotyped and generalized notion of gay men who are often flamboyant and giggly-a lot of these men embrace their masculinity and act like a straight man. The gay men who have muscles are usually more masculine and not have an ounce of their feminine side.
Muscle porn basically refers to the kind of porn that features gay men or straight men who are buff and strong-as opposed to twinks who are skinny. Such is the reason why gay men look for muscle porn when viewing gay porn. They fawn over abs and strong thighs and big butts, mostly because they rely on anal sex when they are fucking. But for men, a gay man who takes care of himself and frequents on the gym is what is considered hot and sexy.
Women do not really think abs are a requirement in finding someone sexy-do they make men hot? Yes, but it is not necessary to want to have sex with such a man who does not have abs. For gay men, it is the abs, muscles, and muscular body parts that are deemed to be arousing and seductive. What gay men find attractive is not really the parts that are hidden compared to women.
