You can choose to register at an escort agency. It’s kind of like an employment agency for sexworkers. Clients can indicate what their preferences are. If there is a match, the agency will arrange for a date. Usually a driver takes you to the location, a hotel for example, or the client’s house. Or you might go to a party with your client or a dinner or a swingers club.
On beforehand you talk it over with the client which gathering you will go to, what the dress code is and what is expected of you.
You can also work as an escort in a club which has an escort permit. Do you want to work as an independent escort? Ask at to your municipality for the possibilities. In some places you need a permit, but not all municipalities issue these. In The Hague for example, it is not possible to work as an independent escort.
