Aren't adult games design to arouse people? How the hell are you supposed to get aroused if you play a game that places you in situations that turn you off? No matter if you play a role, or play as yourself, if you don't find the game hot, then isn't there a failure at the most fundamental level?
Like, no matter how much I like hot succubus, if you put me in a VR game as the succubus, and the game consists of getting fucked by men in POV, I'm not going to be happy, even as much as I enjoy roleplaying. Does that make me a beta or someone who is cringe in your book?
I just don't get it.
Do you realize that most games here have a female MC who fucks all sorts of men? Those are games told from their POVs. Most people don't think of yourself as the protagonists in those cases, but rather as an observer and, if they want, as the men who fuck the woman. Fiction in general is about empathy, but you can always choose with whom you want to empathize.
As for the topic itself... All people want to feel great about themselves, it's our ego at work, but when it comes to sexual satisfactions rules are different. Many women want to be treated as sluts or slaves in bed, the same goes for some men as well. Because there are multiple sources of pleasure from sex—mainly it's the pleasure of dominance, i.e. having power over someone, and the pleasure of being with a great partner, which is directly related to submission. And the greatness of a partner is always comparative. You'll enjoy having sex with a queen way more if you're just a servant yourself, than if you're a king. Moreover so if you, as a mere servant, are making the queen to submit to you while cucking the king, who's much higher in status than you. But the problem with this is that when you treat a woman as a slut, you automatically stop considering her as a "great partner" because she loses a part of her status in your eyes. And NTR allows open minded people to get the best of all worlds.
You put the girl on the pedestal as a "beta cuck" who's her boyfriend or husband, who treats her with respect and love, while she's treated just as a toy by another man, for whom she's a mere slut. This contrast is extremely hot, but not everyone can enjoy it because many people feel hurt and it's too personal for them to accept their arousal. Femdom works in a similar way, btw. The more a girl dominates you, the higher is her status compared to you and the more she's desirable. On the other hand, when it's you who dominates the girl, you enjoy your power over her, which is a different type of pleasure.
BTW, for this reason, paradoxically, it's more common for high-status men to be into femdom and cucking. They're already very high value by default, they need an additional push for them to feel that their women, even hot ones, are actually of a high enough status to be worthy of being their partners. And low-status men and those with low self-esteem usually can't take ntr or femdom at all, because it triggers their insecurities. Normally, though, a person should be capable of enjoying all sorts of stories, be it harems, love stories, or ntr.
