Also threesome porn is not irrlevant to this. A lot of threesome porn is the next step from "lesbian porn made for men", the two woman aren't queer for each other, their queer to please the dude.

I mean if you really doubt it it takes roighly five minutes of 4chan/pornhub/whatever to find a couple of dude talking about lesbian porn. Or you could watch some lesbian porn made fr lesbians, because the diffrence is pretty stark. Or that pretty cool documentry on queer porn. You don't need to take anons word for it. There's a whole world of boobs and scissoring to explore.
