I have come across a great many misleading media that were listed as "yuri" but turned out to be futa/dickgirls. Futa should never be listed as lesbian. It is fundamentally wrong to add a real penis into a scene and still call it lesbian. Futa is futa, yuri is defined as girl + girl, not girl + futa. I direct you to /u/ and shoujoai.com if you still insist on calling futa/dickgirl scenes lesbian.
And I've never seen a futa movie with anything that could be interpreted by the most visually-impaired viewer as a "real" penis. It's always been a strap-on, even when the actresses pretend its real or when that's the premise of a movie. (But that shouldn't be surprising in JAV. I would like to think that most people would be horrified to see a move featuring real r*** - and I admit I don't get the appeal of that obviously popular genre - but we know that it's actually consesual playacting.)
I did take a look at shoujoai.com but it doesn't change what I said at all. Just because other people may share your opinion, it's still your opinion. And, good lord, defending your opinion because it says so on a website? There are websites that will tell you 9/11 was perpetrated by the Jews and the CIA.
My point was, if you don't like futa stuff, don't look at it. It's usually (usually) pretty obvious from the box cover (which most people post) what you're getting into. People are (I assume) buying things with their own money and posting them so we can all enjoy them inexpensively. If the worst thing that happens to you this year is you come across some free JAV that's mis-labeled, I'm gonna say you're having a pretty good life.
