Many of these people are ashamed of their behavior so i think they could be a strong market for this. I doubt it would ever happen though because population control programs need people like this to keep birth rates at a certian level. If you can convince as many people as you can to choose a lifestyle that will means one less human being born then these demons will find a way to create an environment where these people will exist. Homosexuality and next, robots that look like real women.
I think the reason for this is because society shuns this behavior.
As for the pill I rather find a pill to cure cancer than one for homosexuality.
