Please excuse the meme title, this is an actual question
So if two male characters are penetrating the same orifice of a female character, their penises are rubbing together. In literally any other situation, two men rubbing their erect penises together would be super gay. The two males are sexually interacting with each other, not just with their female partner. Therefore, I think that these situations should be tagged male/male, frottage, and bisexual.
But I seem to be in the minority; the majority of posts with this situation are not tagged with male/male.
Any thoughts?
