I want to see a logical story and a logical character. If the character changes her personality because of the player's choice, it will break everything. It would be appropriate if the choice was given from the very beginning and each player built the image and preferences of the character. But here the character already has a personality. There is no need to break it.Lust, mood, hornyness, alcohol and objectives can make you do strange things that you would not do normally. I could see Jane being in such a situation in multiple ways, with some quite funny. Also as a player a lot can pass for me if it's for the sake of the lols to and if the mood is right, why not let Jane experiment a bit? she might come the other way and be more resolute in her sexual orientation. And if it is up to the player's choice I don't see why not give that option to them? If you don't want to see that you can just refuse. It's not like the game is based on putting the MC in situations where she would get things done to her against her will.
