I go to a youth center

There will be one or more youth centres in your municipality, run by adult youth-instructors. Larger cities have several youth centres. The youth center is a place to spend time with your friends, share in the activities of other young people and engage in hobbies.

The web pages for each municipality will have a list of youth services which will include youth centres. If you have problems finding the information online you can for example ask your teacher about youth centres.
