Where the lesbian category means something
] they named the door and the name / was not ours, and we walked / through it anyway [
On most sites the word is a marketing decision. It sits above films made for an audience that is not in them, and the sites cannot tell you which is which because their taxonomy was never built to. These four can, for different reasons. Two because the people making the films are the people in them. Two because the tagging is good enough that you can do the work yourself.
CrashPad Series
The category is simply who walked through the door. No other site reviewed here can say that.
Bellesa Plus
Authorship is stated and consistent. What you get is one taste applied repeatedly, and it is a taste that assumes you are in the room.
EPorner
The free option. Tags are granular enough that two or three in combination will find what the category never would.
xHamster
User collections do what the algorithm cannot. Find one person whose taste matches yours and follow it.
The pattern is worth naming: the sites that get this right either removed the intermediary entirely, or gave you tools sharp enough to work around them. Nobody has solved it with a better category heading, because the heading was never the problem.
