Racial stereotypes are incredibly common in pornography, and are reinforced by the industry in ways that perpetuate sexual and racialized violence. Racial fetishization is common in porn categories and particularly effects the lives of porn stars and sex workers of color, who are often paid less. Like porn, resources around sex more broadly are often created for white audiences. The CSPH has a whole page of resources on sex and people of color, which we highly recommend.
Stereotypical representations often portray trans women as being either sexually aggressive or needing to be submissive to adopt womanhood. But really, trans women can have sex however they want to! The way someone has sex never invalidates their gender identity. Gender is way more complicated than that.
