There are many Turkish NSFW gay accounts on Onlyfans but they are either gays or they don't show faces. Emircan is straight and probably from a conservative family. He would never want to be seen nude or to touch a nude male sensually.
Yusuf has to understand that nobody cares about his physique. People want to see sexy guys being kneaded. Mehmet knows very well how to please the viewers by sneaking a little under the pants. I believe he will have a decent OF channel at the half price of Yusuf's.
