Go somewhere where there are open minded people, a dating service with artsy types, or alternative types, or something along those lines. Set up a profile, explain autism, but don't make it into a label. Write a handful of girls (but don't be like "hey I'm autistic wanna date")... For the first several messages atleast, you shouldn't even bring AS up unless she brings it up first. Once you start to develope a connection with someone, THEN you can explain AS. But if she's really interested in getting to know you, she'll read it on your ad.
Alot of people might say this is self-labelling, but I don't think it is. Not as long as you don't come off sounding desperate.
But by being foward and honest about it, you'll know if she's open minded enough to deal with it and look past it. If she's not, then f**k her, she's not worth your time.
Also, (and I'm not saying that it's not hard for women, just not *as* hard as it is for men, for obvious reasons), aspie men might do better to be willing to move for the right girl if need be. Aspie women don't hafta usually resort to those kindsa means but as males, we hafta make the approach, and we hafta do all the courting. Aspie men may not either, but it would definately help your chances. And of coarse, I'm not saying your efforts are hopeless if you don't. I'm beginning to feel alittle more hopeful today that at some point in time I will meet Mrs. Right. Of coarse, Mrs. Right might not be in my home state, and of coarse, you could also say an aspie girls' Mr. Right may not be in the same state too.... But I really wanna believe in soul mates, rather my soul mate is in NC somewhere or in another state somewhere, or even in another country for that matter (but I'm not moving overseas at this point in my life).
but be wary of women who'll try to drag you in and lead you on and disappoint you, there are alot of them. I can tell you some signs so you'd know when this is happening.
