All getting laid as social therapy has left me is with the doctor at the local free clinic knowing me by first name basis, some of my belongings stolen and nearly ending up in jail because I have stress-related mutism whenever I’m under stress and an officer thought I was being avoidant. (Long story).
The kind of women you pick up if you try to get laid when you’re on the spectrum are women who don’t really care too much about themselves. Bar whores with sandpapery voices, fat chicks with personality disorders, women with low self esteem and bipolar women. I’ve seen it with some of my friends from my support group.
The kind of women that would ordinarially have some sort of care for themselves are ordinarially repulsed by some Autistic quirks and have nothing to do with you. Either that, or they look like men.
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.
