It's laughably retarded to be on a website like this and point at any orientation, or fetish, and question why it exists or immediately assume that no one will like or participate in it. Seems to me like you're willfully ignoring the incestuous shota and loli in the room. But it's interesting to know that gay is where the line is drawn.
The artist had, back in may of last year, stated their stance on including homoerotism in the game had shifted and they were not only willing to, but were actively planning to, include such scenes. Sorry to those of you who missed this or just ignored it. Just to get those of you insecure enough to care ready, they are also planning on adding Zoo content, and had stated at the time that, much like the lesbian scenes, both of these types of scenes will have content filters and be entirely optional. To be clear, I probably won't even go for those scenes, but I am sane enough to not give a shit about what people are getting off too.
For those that are too stupid to understand, go back to getting off to your hetero incestuous shota scenes and ignore the people who will enjoy the optional gay. It genuinely shouldn't impact you, if it does you're the problem.
