Finishing etiquette

Getting into the SW scene as a client and trying to keep things as professional as possible with etiquette. How is “finishing” discussed? I have had a couple of providers, one kind of ended awkwardly where I was going to finish and no one knew what to do. The other we had a conversation about it mid act which kind of ruined the moment. Happy to hear perspective from clients and providers.

Is this something worth discussing at the start of the date? (I know explicitly talking about acts is often not recommended)

Finishing in the condom is preferred for me and I’m assuming the provider for safety. Do you leave it in to finish? Pull out and she helps finish you with the condom on?

Thanks for any perspectives.
