Coworkers. People at your college. Just ask people that you know. If you can't get past your own insecurities regarding your aspergers, you're never going to go anywhere.
For my first portrait shoot, it was November and I just asked my neighbors when I saw them outside if they wanted to get any fall photos done. They accepted and I warned them that I was new and wanted practice, but they were willing to give it a shot. In the end, they were thrilled with the photos and I got some much needed practice and had a blast.
The problem is not finding people I think, it's more like approaching them without seeming to be some sort of creep or pervert.
Why would they think that? Are you looking to shoot nude photos or something? If so, I suggest avoiding that until you're much more comfortable with your own work.
Do you not have ANYONE that you talk to on a semi-regular basis? All you have to do is say "Hey, I'm trying to get into photography and I'm looking to get some more practice. Would you ever want to get some pictures done for free?"
I say free because you're new, and you're definitely not ready to charge. It's a fair trade.. they get free pictures to throw up on facebook, you get practice.
