Go to artist to commission futanari porn. I ask if he draws futanari or shemale porn and calls it 'futa'. He doesn't understand. I send a illustrated diagram explaining the differences of futanari and shemales. He laughs. "it will be a good futa sir" I finally get the commission. It's shemale porn.
I don't personally draw a very big distinction between "futanari" and "shemale", like, we're all here because there's that bonus equipment down there.
But while I don't get the common complaint about the two being confused (all good for me as long as I like the art itself), it's gotta fucking *suck* to pay for a commission on a described specific kink and have that delivered wrong.
