I do some bdsm services both ways giving+receiving, but as pro subbing is harder to find / more niche than all the different dommes out there, I feel I get booked for that more often
You need the basic rules, obviously traffic light system are popular safewords or “mercy” and no permanent marks left.
I don’t let anyone restrain me on their first booking and i state that on both the profile and when they ask for it. Explain you need to build up trust first with successful other bookings!
Actually have been known to let clients I know after a few meets tie me up or blindfold me. This probably won’t be recommended by most people, as clients can quickly change behaviour, but I’ve had no problems
You can also get the soft handcuffs that are sort of round your wrist big enough that if there was an emergency you could slip out of them. But I’ve done the full thing too- thigh restraints, under the bed etc.
Also have experience with using professional dungeons- these are usually super expensive per hour tho. I have always got the client to book and pay for that upfront. So unless you plan on working a lot is not a good idea to be permanently based in one (and you don’t need to!!) With some of your own kit you can use any room. If you don’t have a specific piece of kit yet, if the client wants to use it they should purchase it for you
I also have a weirdly high pain tolerance so usually OK with some more extreme impact play, I do worry that a client then treats another escort with same level of pain will be unbearable or get them into trouble

But all you can really do is simply base it on what you’re personally happy with. Do
not be afraid of saying no EVER, or halting the scene completely Don’t injure yourself
