I work in a naked spa. It's exhausting and so much fun – but every now and then we have to stop people from getting intimate.

• Felix Kühn manages the sauna at a "textile-free" spa in Berlin, Germany.
• This means guests must be naked to access its pool and sauna.
• "It's a very physical and exhausting job, but I have so much fun with it," says Kühn.

This as-told-to essay is based on a conversation with Felix Kühn, a 29-year-old sauna manager in Berlin, Germany. It has been edited for length and clarity.

I working started at Vabali Spa Berlin in December 2014. I met a guy on my first day at university who told me that they were looking for people to work at the sauna and he asked if I was interested.

I later realized that studying at university is not how I learn best; I'm a pragmatic person who likes to work physically with my hands. So I decided to drop my studies and start working at Vabali.
