Do you autists really care that much about a pussy that's not even going to be visible 95% of the time?
How can you even tell the difference in cases where the dickenballs are in the way and you're not familiar with the artist? If you like a picture and find out that there's no vagina behind the package, are you going to flip out?
At the end of the day the appeal is the dick and futa has turned into an umbrella term for women with dicks, the specifics regarding balls and vaginas are just semantics.
