That's not how that happened. You didn't take her by force. She feeds you the flower, you get all demony, but you resist it and don't attack her. She chooses to "calm" you, after finding out that you would most likely break out and attack other women. It's definetly dubious consent and I do think it would be a potential problem, but it's not by force.As for the corruption not being rape, that depends on who is making the interpretation. I was also thinking about that scene where ashley gets tricked into feeding you that flower, and then you take her kinda by force, that one would be easy to classify as rape.
