It's misleading mostly because it is not, in fact, rape.
It's closer to people being influenced/manipulated into sex, which is an ambiguous case of manipulated consent, ergo NOT against the consent itself. If that is rape, then every sexual relationships are too, because everyone is, in a way, influenced one way or another to the decisions that lead to them having sex. Since not every sexual relationships are rape, then this isn't either.
Granted, here the guy does have a cheat code because it is sci-fi, but the same principle applies. Someone charming successfully getting into someone else's pants thanks to their charms isn't rape, it's influence and/or manipulation. That's the same but with superpower.
MC gets the consent using his ability (his "charms"), therefore it's not rape. End of story.
You could debate all day about the ambiguous definition of what a consent is or isn't, sure. Doesn't change the fact that mind control and rape are two different kinks. Some people have one without the other, some people have both. And, honestly, that diversity of preference should be the only necessary proof that these two kinks are in fact different.
