Dating sites in general are hot garbage. But...I have had some luck with a few non-traditional sites:
1) Meetup.com. Meetup is free, and sets you up with groups of people with similar hobbies and interests. It isn't a date, but a group activity. Most people are single that attend, and most people are also awkward. Worse case scenario, you make new friends
2) City Swoon. City Swoon is a speed dating service, and I ended up dating someone Iet we the them for awhile. They do 10-15 mini dates, and then you can contact people you like through their portal the next day. A bonus for the one I went to was all the other guys were kind of dicks.
3) Acebook.com. I just started using Acebook, a free site for the Asexual community. So far I like it. There is no pressure, and you can just talk to your ladies about stuff you both like. I've had several women contact me so far. The Asexuality Spectrum is a bigger Spectrum than ASD, so it doesn't mean no romance or no sex ever.
4) Tawkify-Tawkify is a matchmaking service. It's not cheap, but if they can't find lightening in a bottle they refund your money.
I've tried every Aspie/ASD dating site and app out there, and they just weren't for me
eHarmony has sadly turned into a scam website with predatory billing practices. I would avoid them.
