Traps, or "otokonoko" are very popular in anime, and IMO even getting more popular recently. With stuff like Astolfo and Shimakaze-kun.
Trans people are also getting more spotlight in western media these years.
But I notice most of the trans portrayed in western media are trans women.
Trans men, i.e. women who take testosterone and have an artificial dick, get very little coverage in comparison.
And I don't see many "tall and handsome, but has a vagina" characters in anime either. Outside of stuff like Ogami Sakura and Stella, who are not handsome, but super muscular joke characters.
What do you think is the reason for this? Or are there actually equal amount of trans men and "onnanokan" out there that I just haven't notice?
