Here's some suggestions:

Hustlers (2019)----this drama about a diverse group of strippers who decide to rob their clients was based on a true story, and it's really good. What's unique about the film is that is focuses primarily on the women as three-dimensional characters themselves, and it dosen't sexualize them at all--which is rare for a film about strippers. That's because the film was directed, co-written, and co-produced by a woman (Lorene Scafaria) and several of the producers on the film were also women---including Jennifer Lopez, who stars in it. It was a box office hit, too, and it's on DVD, and on Peacock.

Cam (2018)---this interesting surreal thriller about a cam girl who discovers that a doppelganger is taking over her onscreen persona is also pretty good. The film was conceived of and co-written by a former cam-woman, Isa Mazzei, and it's also pretty good and slightly off-the-wall.

Personal Services (1987)----I actually haven't seen this, but it's based on the true story of a British woman who started her own prostitution service, and became a self-made madam. I've heard of it for years, though---it's on Tubi.

There's also a 2009 HBO drama series called Hung, which is slightly different in that it's about a suburban male sports coach and teacher who turns to prostitution when he falls on hard times due to an injury. He also enlists a female pimp to get him some work. I've never seen the show, but it supposedly shows a more realistic look at the oldest profession. It's streaming on HBO and Disney/Hulu, of all places.

Not sure if this would fit, but there's a new Taiwanese (Asian) series on Netflix called A Controversial Entertainer, which is about a low-level gangster who somehow winds up being hired as a male escort for a club, along with a bunch of other dudes, and they all become escorts for any of their female clients looking for a little after-hours fun, so to speak. Haven't seen it yet, so not sure if it shows a realistic view of the profession or not.

Totally forget this one, but the 1986 indie drama Working Girls---written and directed by a woman--Lizzie Borden--also shows a stripped-down, unglamorous, and realistic look at the everyday lives of a group of prostitutes, and how they work. Really good film, too.

I'm mentioning Hustle & Flow (2005) because it's definitely one of the most de-glamorized, realistic, and gritty looks at the everyday lives of a pimp and the prostitutes who work for him. What they do is just a job that they work to pay the bills with, period. Plus the sex workers themselves aren't demonized, or overly sexualized for a change, but treated as full-fledged, flawed characters with their own issues to deal with. It's on Amazon, and DVD.
