My question is, "to what purpose". If the point is to overcome the awkward approach, why bother to change mannerisms that took decades to form into habits when you can bypass this altogether through matchmaking sites and speed dating and such? If the purpose is to learn how to seduce a woman/man, there are already lots of websites and books already dedicated to that subject. If the purpose is to build conversational skills, manners, listening ability, how would this differ from an ordinary interpersonal communications college course?
Personally, I wouldn't be interested in this, because I'd rather not have to date a large number of people. The dating experience is not an end unto itself for me. If I date, it's because I'm looking for a life partner. If I find someone compatible who is looking for a life partner as well, it stands to reason that a minor screw up isn't going to be held as a fatal flaw, especially since I plan on being fairly upfront about not being very outgoing and mentioning AS no later than date #2. Other people may date for other reasons (sex), but I am not one of these. Some people date for just the fun of dating, but for me, the fun depends entirely on how easily I interact with the other person. If the interaction is easy, it's fun for me and I know there's a possibility for a significant relationship.
Further, my fronting skills are so practiced that they are already automatic. As long as I'm paying attention, I appear to be perfectly normal (it's paying attention 24 hours a day and the energy that requires that are my true limiting factors). I regularly fool people that would never guess I had AS or social anxiety or w/e else. What they don't realize is that what to them is natural, to me represents the results of a lot of mental preparation and practice. I don't consider myself to be "faking NT", as much as just putting my best foot forward, presenting myself in the best way I can, etc. I'm no more important than anybody else, and if I'm going to ask people to tolerate my oddities, I should at least make an effort to be considerate of them. I've lost a lot of my egocentrism with age
