One of the first articles I read as a teenager about Dominatrices was an interview with some very young women who were working in one of the big Dungeons in NYC. They basically described very minimal training, but a big payload. Show up in boots and pretend you know what you're doing, basically. Their sessions were mainly verbal humiliation, foot fetish, and service topping. From what I gathered these young Dommes learned by letting the sub teach them by topping from the bottom. I have to admit when I was a young Domme I've also used this method to learn a few things, like saline infusions. A sub approached Me about doing it and I was upfront about not knowing how, so I let him teach Me, he'd been doing it solo and with Dommes for 40 years so I trusted him. He got a session and I got the skillset. Women that want to stick around in the business learn to learn, and others just coast through on looks until something else comes around or they lose clients once they get a reputation as not being skilled. Not sure which Julia was, but I can confirm from a reputable source she was in fact a successful Domme at Pandoras for a while!
