I have a theory that the masturbation is something of a frustration which men do so that they can fully "let go", something that for various reasons (shame, guilt, fear etc) they can't do when they have sex. So masturbation "allows" men to be free of their obsession with pleasing the women and they can finally focus on themselves. (not that it's good) So i think people that get addicted to masturbation have this incentive to get addicted to it because they can experience things they can't experience in partnered sex because their focus during sex is on the woman. And men masturbate so that they don't have to ask women to do stuff they would want them to do. In my case, i can 100% say my focus was always on the woman and how to make her feel good to the point i wasn't feeling pleasure at all. I could never asked them to give me pleasure and even if they offered to i felt wrong about it. I was always satisfied on pleasing women, even if it wasn't sex related. What is your opinion?
