Well that is a little odd.. I never heard of such a thing.
There are erotic healers all over the world, many of whom operate in legally oppressive environments. I forget which European country it is - it may be the Netherlands - but people are allowed to hire sexual services, including sexual counselors and erotic healers, as part of government health care.
I know it may seem odd, but if you think about it, sexual health is just as important as any other kind of health. People who have a history of sexual trauma, shaming, harassment, or other pressures, could use a safe, secure, professional and sexual healing environment. Unfortunately, most countries have laws which are based on shaming sexuality, so people never get the help they need. In Europe I met a young woman with her masters degree in clinical psychology, and she was a sexual healer. Sometimes her work involved consensual sexual acts, other times it was just talk therapy. In North American law, such a professional would be deemed equal to a street sex worker who is merely subsistence level. Our laws are draconian.
I mean, look at our basic premise of sexual education in America. It's mostly based on sexual anatomy, and biological facts. Yet even that is controversial, for some reason. In sex ed, there is never the opportunity to discuss healthy relationships, how to sexually please your partner, how to avoid sexual shaming and causing emotional harm -- there is no roadmap for what having a healthy sexual being would even look like, because it's deemed too "liberal" or something.
IMO if we had more sexual healing services, there'd be less rape and domestic violence.
