Sorry for the delay answering! I thought the thread had pretty much finished so stopped checking so regularly!
Generally, it can progress in two main ways. One is organically, like any normal dating situation... you meet to have a drink or dinner, and you both know you'll be seeing how it goes, and if sparks fly you end up in bed. I actually don't tend to do this. For safety and my comfort, I always have what's called a 'social meet' first- I'm explicit that it's purely social and normally it's a coffee in a public place. By the time I invite someone to this meet, I've already verified they are a good match 'on paper', that principle boundaries and preferences are understood, and there's a general positive camaraderie. If the social meet goes well and we are all feeling the chemistry, and have a gut good sense of trust, safety etc, then we'll say by the end of that coffee, that we would like to invite them for play, if they would like that. It's always me who does this. I tend to know if DH is happy, whereas I'm a tougher sell. I think it's also nicer for the play partners, because they know the woman is really deciding and keen. (Generally there is a norm on the scene that the women initiate and approach, because consent is taken very seriously). If I'm in any doubt about how I feel, then it's a no for me- I follow my gut, even if I can't rationalise it. If I have any doubt how DH feels, then I don't decide during the meet and check with him after.
Then we arrange a date and time with the explicit intent of having sex. Of course, everybody can still cancel/pull out or abort on the day, in line with whatever they are feeling- but it's more explicit intention than for a general date with somebody you haven't slept with yet. Often there's sexy talk before this date, plus more detailed discussion of any sexual boundaries and preferences.
Many people meet in hotels or clubs. I prefer to invite people to our home. It's more personal, less pressure. I have a very private home, no worry about neighbours etc, and I know I'm safe in my environment. I would never do this if a single woman, but with DH, it feels fine.
Some times, this 'date' can also be very sociable - especially with women and couples, it's likely to be a little sexual from the beginning, in that we might all touch in a way you wouldn't with friends, but we may well sit down for a drink, or even dinner and talk about a mixture of normal things and sexual things, then at some point that feels natural, we would suggest moving it upstairs- or start having intense fun on the sofa, before moving it upstairs...
Two hours later, or whatever, we all come back down, normally share another drink and chat, say thank you very much that was lovely, and say goodbye.
DH and I would then connect ourselves.
