Anyone would be embarrassed to be seen masturbating-you are actually revealing your vulnerability and what makes you weak. This is hot for a lot of people because masturbating is supposedly a personal thing, it is supposed to be sacred. Since they do not really want to have sex with one another, perhaps as a boundary between being friends or maybe just for the sake of being dirty-they opt to just masturbate with each other. In usual scenarios, the plot usually involves two gay men who are probably just casual friends and just managed to be horny at the same time at the right place. It is a kind of voyeuristic porn wherein both gays will jack off in front of one another-no touching or anything, sometimes they may allow subtle touches or a few tease here and there but the idea is to stroke their penises to the pleasured face of one another. In short, they will use each other as the fap material. This is called mutual masturbation-it basically refers to the kind of porn wherein both participants will masturbate to the view of one another masturbating. It is quite normal to try different dirty and kinky things on the bed instead of doing the usual sex we all know-one of the popular acts to do does not actually involve having actual sex. The kinky session happens not just in porn but also in real life.
