I think you're just going about it all wrong.
One of my best friends had a stepson who was mentally retarded. After he was of legal drinking age, we used to take him to our favorite bar.
He sided up to more women than anyone else could, and most often he picked the best looking one's to boot.
In his case, it was because he had no concept of where he was on the spectrum, and we always treated him like he was normal. He had no concept that the 'pretty' women were somehow 'better' than he was. And he didn't treat the 'pretty' ones any different than he did the one's that fit some of your descriptions. (It drives the pretty one's crazy when you treat all of them the same)
He treated them as if he could have his choice of anyone, and if they didn't respond, he simply moved on to the next.
There are some other skills that can be used to increase a woman's desire to be with you, but this isn't the time or place to go into them.
You really think Asperger’s Syndrome and mental retardation is the same thing? If you do, then your advice probably is not worth that much.
