Yes, most people know about drug and alcohol rehab. If they haven't been to one themselves, they're familiar with someone who has had to face those demons in a residential setting. But sex rehab? That's a joke, right?
I find my home country, the United Kingdom, depressingly antagonistic when it comes to the subject of stripping and strip clubs, but I've always found the US to have a more tolerant and lenient attitude to the legalized sex industry.
