I don't really mind that so long as she will be able to perform in the same way a male character would and have the same animations (orgasm).
I just wonder why you have to lock a penis behind a cosmetic item, lol. Will she have to get boned by a futa before being able to sprout a dick, or is she just going to have a weird penis-looking dildo? If its the latter, I'm kinda disappointed ngl since you already have actual futanari in the game.
Since you said it will only be a cosmetic, does that mean all her sexual animations will be stuck as female, even if she has the cosmetic dick attached? If so, that is extremely disappointing.
--> also, the heck does having a dick have to do with her personality???? LOL
