Why do these performers have so many more scenes than the Brazilian ones?

Career structure. A US performer shoots for several studios over years and every credit lands under the same name, so the filmography stacks up. The Brazilian industry works through a much wider cast with fewer scenes each. It says nothing about who is better.

Are the scenes softer than in the other groups?

Less extreme, yes. Anal is still the standard act, but group scenes are uncommon, condoms appear more often, and there is far more solo and girl-girl material. Check the tags on a profile to be sure.

Who tops in these scenes?

A man topping the trans performer is the most common single role tag, though it is a plurality and not a majority. Scenes with a cis woman in them are as common here as anywhere on the site, and those flip the role. Each profile shows its own split.

White trans pornstars (361)

This is the group whose names you already half know if you have seen any trans porn at all. It is heavily American, clustered around Los Angeles and Las Vegas with a European minority, and it holds the longest and best documented careers in trans porn.

Natalie Mars has more measured scenes than anyone else on the site. Lena Moon, Jade Venus, Izzy Wilde, Brittney Kade, Gracie Jane, Casey Kisses, Aubrey Kate and Korra Del Rio all carry catalogues in the dozens. That is a structural difference rather than a quality one: an American performer signs with several studios and shoots across them for years, so her credits pile up under one name, while the Brazilian side spreads the same volume of work over a far larger cast.

The scenes are more produced and less extreme than the Brazilian material. Anal is still the default act, but condoms turn up more often, bareback much less, group scenes rarely. Scenes with a cis woman in them are as common here as on any page of the site, and there is a real amount of solo and trans-on-trans work.

Post-op performers are a small minority here, as in every group on the site. Izzy Wilde is the one with a deep catalogue.
