I can only tell you my experience.
my CB chat window says 'so and so wants to start a private'.
I decide if it's a good time or not.
Sometimes I PM them to find out what they want (since not everyone reads the bio and knows what my limits are).
if it's a good time (not interrupting a busy room with a good atmosphere and lots of play/talk/tipping), I click accept, it starts (your former audience sees a 'private show' message instead of your live stream, and your cam thumbnail doesn't update from what it last was before accepting the PVT. only the guy paying for PVT sees you, unless you have 'spy shows' allowed, and then it's possible others will take a peak at it).
then I say hi and ask them how they are and what they wanna do, and we go from there. very much just a feeling out process.
I try to keep a bit of a stripper sway goin. doin something nice (flexing, dancing, whatever. there's plenty girls can do (playing with tongue/hair/tits/touching their body, adjusting/teasing with their clothing, etc), to ensure I'm not too boring while they're not asking for anything specific, since they're paying for every second of it. but sometimes they're guys who just wanna sit and chat and they tell you to chill, like 'it's too distracting', and they just know that you have to pay for that kind of one-on-one attention. I've had PMs where I was largely just typing, not even talking. Of course, some people want a private and recorded cumshow of their own, so if you don't do cumshows at PVT rates, you might wanna PM first to make sure they don't get disappointed (being a service industry it always pays to be considerate -- I even apologized profusely and then went through support to reimburse a guy once after a totally innocent misunderstanding about the PM he wanted that I couldn't do, and he opted to let me keep the tks anyway, maybe seeing that it wasn't me trying to scam him out of anything, or liking what little he did get before the misunderstanding came to light -- either way the result is a positive experience of good intentions and professionalism and kindness with all parties involved. Other times it might be like 'ok now do this', and I have to just say 'sorry babe, no [insert request]--that's one of the hard limits* on my bio', and it's simply a no-can-do, buyer-beware type thing, because I did my best to list what I don't do).
*'hard' and 'soft' limits are BDSM jargon for things you're iffy about or never want to do.
another thing for newbs to be aware of, is that 'Skype', 'paypal', and any '@email.com' phrases are blocked by CB -- no one gets an alert 'your message wasn't sent', you just assume it did, unless a lack of response tells you they didn't get it. So, some members aren't aware of this, nor are new models. So, if you ever see someone give you their email line by line

that's why, he's not just weird
or if they spell it '5Ky pe' or something like that....it's to avoid the message filter.
Make sure you read the terms and conditions so you don't accidentally agree to something against their terms not realizing it might be a problem. it could get you banned or blackmailed.
a lot of mods will silence greys (no token guys) who ask you for PMs, because usually against-terms arrangements are the only reason they'll try to talk in "private" (I scarequote 'private' because of course CB has a temporary record of all such discussions).
if you put an email in your bio, someone told me you have to put it in the wishlist section so that the word filter doesn't remove it, that way you can write it normally/easily copypasteable. Make sure you're clear about what it's for so that you reserve the right to politely ignore all time-wasting correspondence -- maybe it's an email for giftcards, maybe it's an email to arrange panty sales. whatever. It means it's not just a free offcam contact, but purely for doing business.
