Arguing the semantics of what is or isn't gay on this website is about the most pointless thing imaginable, but for the nobody who asked, my two cents is this;
If there is a cock and a pussy involved, it's not gay. MalexFuta, FutaxFemale, FutaxFuta, and MalexFelmale fall into this catagory.
If there are only the same parts involved, then it's gay. MalexMale, FemalexFemale, MalexTrap/Femboy/Trans fall into this catagory.
Although much less common, cuntboys also count as a pussy for that dynamic. It's pretty simple and straightforward. Which is why a game like this earns some degree of my ire, if only by association with the poor tagging rules. Combining both Futa and Trans into one tag is far too broad, when the related fetishes couldn't be more different, and in my experience, people who like one generally strongly dislike the other.
Hell, if a mod sees this post, I would personally be willing to go through the entire tag myself to separate the two properly. It irks me to an unimaginable degree.
