I mean the game has sort of "gay" stuff in the game, if you count Futa as one, since its basicly just adding a dick to the girls as an option.
And you cant really be strait with a girl that only has a dick on them, unless they are herm (in my logic anyways). So you could just ignore the breast, and you could call them boys by then.
With all that being said, they dont seem that keen on making gay to the game, but are fine with futa.
But you could always just ask them on Discord and see what they have to say.
