Wait what. Most netorase games are also about corrupting the female.
Personally that desinhibition of the female is what interests me the most. And I think netorase do it better, as ntr games are generally loaded with unnecessary dramas and even dark/desperate atmosphere... not really the fun atmosphere of a wild game.
But you can have that feeling of desinhibition in swinging or even female protag games.
I think we like them for different reasons then, which is completely fine.
I like sharing games where the emphasis is on the couple doing these things because they're in sync and both agree they find it hot. I personally am not interested in the idea of 'corrupting' the female (though that may be an incidental effect in those setups), but more that the girl
wants to do these things with her boyfriend, it's the dual agency that makes it hot with both of them exploring their desires. And sure, maybe what you or others are calling corruption are what I'd call 'some initial discomfort of the girl in new situations' - and that can certainly add to the sensuality - a la "uhhh I've never done it with a guy that big before, I hope it'll be okay.."
This is a very different motivation than the classic 'female corruption/fem protag' games, which again, not putting down fans of that, but it's not why I like sharing games.
