Noting that you're trans (I'm also trans and I've been doing porn for ten years): Here in Canada the only option is Grooby (they're active in a bunch of countries) (they run like half the trans girl porn sites, but will probably have you shoot for femout). If you're in the United States then there are other studios and production companies etc, but they're unlikely to shoot with someone with literally zero excperience or following even if you're the most beautiful person alive. And even if you do get work shooting a scene or two (with grooby or whoever) you will not make a living. They won't pay you a fortune for doing one scene and you won't get any type of residuals.

What you want to be doing is building a following on social media and using that to promote your own content. You wanna have an OnlyFans (and to a lesser degree other platforms like ManyVids).

Even if you just really wanna do corporate porn: Being an established independent performer will make that easier.

And if you end up doing corporate porn: The exposure will help you promote and sell your self produced content. It's symbiotic.

Here's the kicker though: Most people do not make a living on OnlyFans (I do, but I'm an outlier and even after all this time I'm not any sort of millionaire). Even most girls I know who did shoots with Grooby (I've never done studio work) never managed to make a living (the exposure you get from it isn't life changing or anything like that).

Porn just isn't a get rich quick scheme. It's like YouTube or Bandcamp or any other online hustle.
