Hey I have the right to my opinion about what I like sexually, and since I'm gay I don't care to see a female in a sexual way. If I was straight then I'd be all for it. That would be like me questioning a straight guy not wanting to watch gay porn.If this is something that disgusts you, then you probably shouldn't be hanging around profiles of straight men to begin with honestly.
The thing about OF is that the guy isn't bound to anything like one would be for a professional gay porn studio, there's a good chance he's gonna post content of him collabing with who he prefers in regards to fucking, and if you decide to subscribe or become interested in said guy you really shouldn't be surprised or complain about them putting out straight content...seeing as that's what they are.
That said, at least he made the effort to get himself on camera rather than have everything be from his POV, it isn't exactly like how you're making it out to be some POV Bangbros video focusing only on some big booty chick.
If there's one thing I can't stand, it's when a straight guy gets criticized for being himself. They shouldn't have to feel restricted with what they post, they are simply allowing you to take a look into their sex life. One of the oddest things ever, is when the gay audience ogle over straight men, but then become sickened once straight men start doing straight things. Why torture yourself by sticking around?
In addition to that most (not all) of the people who frequent this website are gay men. So if a gay man sees a video of a hot guy they're attracted to having sex with a girl and they don't like it what else do you expect them to think or say??? Plus most of the followers and fans of all of these fitness model guys on social media are gay men.
When the video of Brandon Harding and his girlfriend having sex got posted all over the web it was a huge thumbs down for several thousands of people. Simply because by popular demand people usually do not seek out those videos to see the girl, they want to see the guy. Especially if he's hot and popular on social media. If the guy is unknown and not that attractive but the girl is, then people seek out those videos for the girl.
