The erotic massage scene in Turin is as tiny as the Asians that work in them. Massaggi Naturale (https://www.massagginaturale.it/) at Via Onorato Vigliani 185. There are more studios around town but they don’t really advertise. You can also check Bakeca (https://torino.bakeca.it/) for some classifieds. Expect to pay between €30 and €70 per hour depending on the service.
