My perception of "everyone" has nothing to do with LGBT and based only on Itch and other popelar websites with 18+ games, comics, etc.
And 99% of the time, it is the tag “futanari” that is used on such sites for characters with dick and tits. So, it is de facto (not de jure) non-alternative tag for describing such characters.
If you think everyone around you is an idiot, feel free to do so.
But stop bringing in things that have nothing to do with the motivation of developers to choose this or that tag, such as LGBT.
