Dating apps for Aspie son

afternoon. New to this bit of NAS. My eldest lad is 27, just back from travelling for 3 1/2 years in Australia and New Zealand. I know he wd love to have a girlfriend/partner so I'm just hunting around to see if there are any sites where he might meet people. He gets irritated about being AS and sometimes prefers not to say. He's living at his dad's in Surrey at mo whilst he looks for work. When I get to catch up end of this month, I'd like to be able to slide some info his way! Any ideas??
