As a teacher who has had several autistic (Asperger's) kids, I will say that although able to function in classes fine and able to carry on a conversation, and are not "handicapped" by their condition in most senses of the word, most of them were what I would call socially awkward. Not that they replied inappropriately but they just didn't engage in a comfortable way with others. If you are awkward and stiff, it isn't going to make many women want to be with you, until you find someone willing to give you enough of a chance that they will get to know you really well, past the stiffness. This is more likely to happen if you become friends with a woman first and then falling in love just happens. I don't know if this is you, but I would bet there is some sort of behavioral/social therapy that could help if it's you.
I recently met a guy online (yep. Hearing people are single too!!) We met at the coffee shop and as we talked it felt like a job interview! Rather than easy conversation, he asked me, "So, where do you like to go?" A rather wide open question, right? Then asked me what I like to do. Then, after more interrogation and several moments of awkward silence, he asked me if I had any questions for him. We parted (and I said I wasn't interested in dating and he said he'd like to be friends too). A week later he called me to get together again. He called me 9 times in 2 days, and didn't leave a message at all. He is a very nice guy. But he comes on WAY too strong and seems incredibly needy to make a friend, and desperate to get together with me, despite not having good, flowing conversation. I'm not sure why he enjoyed it so much, I have to go back to desperation. He has no idea that is how he comes off. I even tried telling him! He just doesn't get it. So, my advice is ask a woman you know for pointers. Tell her to be BLUNT. It may not be pleasant but it could be really worth it.
