Everybody has a first time. If this is your first booking, you are welcome here, the same as a man who has booked many times.
You do not need to know how it works. Call or WhatsApp us and ask anything: the rate, how long, where she meets you. Tell us it is your first time if you like. Nobody here will judge you.
Take it slow. Ask for more photos of the girl before you pick. Anything special is agreed before the booking, so nothing comes as a surprise. You pay her in cash or UPI when she arrives, not before.
