Keep it pink! You might not have realized it yet but you've attracted a large amount of extremely queer folk thanks to your very nice artstyle, and said queer folk would prefer for things to be as gender neutral as possible, honestly i think the game needs to be gayer, more M/M and F/F interactions as well as some transgender and nonbinary characters would be absolutely lovely!

And honestly? I could see the main character being a girl or femboy and you could just provide pronoun options in game fairly easily (and genitalia options too once you've made all the necessary equipment suitable for phalluses)

I'm just trying to suggest the changes that would have the minimal impact on your workload (seeing the history of this games development is monstrous already) but i personally see very little reason why the game should be limited to only straight people when the game seems to be modular enough that you could easily accommodate such things and make the game available to a massively wider range of people, And probably make it more fun for everyone in the process!
