Is ladyboy the same as trans here?

It is the genre term the Thai industry uses for its own performers, and it maps onto the same people. We write trans in our own copy and keep ladyboy where it is the literal name of the material.

Why do the Thai performers have so few scenes listed?

Because the Thai catalogues credit their casts badly. Scenes often go out with no performer named at all, so a working career shows up here as two or three entries. That is a gap in the source, not a measure of how much someone has shot.

Are there Japanese or Filipina performers?

A few, and they sit on this page instead of getting pages of their own: the numbers do not support splitting Asian into national pages yet. The nationality checkboxes in the sidebar give the breakdown.

Two different things sit under one label here, and it is worth knowing which you are looking at. Thai and American performers make up most of it in roughly equal numbers, with single names from Japan, the Philippines, Cambodia and China behind them. On the Thai side ladyboy is the working genre term and the material comes out of a local industry with its own conventions; the American half shoots for the same studios as everyone else on this site.

Kasey Kei carries more of this page than anyone else, by a wide margin. Behind her sit Venus Lux, who worked out of San Francisco through the 2010s, Yasmine Lee, shooting since the mid 2000s, and Leilani Li, who is Filipina rather than Thai. The Thai names indexed here, Ying, Aye and Peemai among them, mostly have thin filmographies on our side because the Thai catalogues are badly documented.

Almost every scene here has a partner in it, and almost always a man. This group carries the site's largest share of scenes tagged with a man topping the trans performer, and gangbangs are rarer here than on any other page. Masturbation and POV framing still turn up a lot, which is a habit of the ladyboy catalogues.
