I think the problem was more about the futa scenes rather than the gay ones. Many straight oriented games that added the gay option down the road and mostly went along fine(C**kwork Industries for one). And some of them that added the 'unusual' fetishes later on did get a lot of hate comments like what happened now.
Sad to see you removed the gay scenes, but it is your game, in the end what you say goes, no matter what other says. The last decision is and always will be yours. People gotta respect that or leave. Not like they actually pay you to get this, right?
Good luck with the game though, this one got good potential.
