The age gate is the notice that opens this site and the line behind it: every client and every therapist is twenty-one or over, whatever the occasion.
The first thing this site shows is a short notice about age, laid across a darkened page. Confirm it and the notice closes. That notice is the age gate, and it states the line that runs through every booking made here: twenty-one or over, for anyone who books and for anyone else who will be in the room.
The line sits above adulthood on paper, and it sits there on purpose. Amsterdam draws a young crowd at weekends, and many of those visitors arrive in groups with a plan hatched somewhere over the North Sea. A threshold at twenty-one keeps every booking to people with a few more years of knowing their own minds.
A birthday on the day. A stag weekend where the groom is twenty-one but one of his friends is not. A booking placed by an older friend on behalf of a younger one. An offer to pay more. None of these changes the line. Sending a booking message is your own statement that you, and everyone else present during the session, are twenty-one or over.
When she arrives, your therapist may ask for a look at photo identification. She glances at it and gives it back at once, and she keeps no copy, scan, photograph or written note of anything on it. If she cannot be sure that every person present is twenty-one or over, she goes before the session starts and the visit ends at that point. Everyone listed on the roster is twenty-one or over too.
The notice is not decoration. It tells a visitor, before reading any further, what kind of site this is and whom it is written for, so nobody wanders in at one in the morning without knowing. If you are under twenty-one, close the tab. If you are twenty-one or over, the first-timers' guide is a calm place to begin, and the WhatsApp booking entry explains how a first message works.
