I'm 39 this month and have similar issues. One of my problems is that I'd like to have a child or two more than being in a relationship. This doesn't bode well, I know. I guess I've known instinctively in my whole adult life that I'd be a terrible mate if I ever got coupled. Besides not being a reliable and caring person I have sensory issues with both kissing and doing the man's job in the bed, tbh. I guess I'd pass as a parent if I had a child, I've practiced caring for and playing with other children in my family and acquaintance. The hard part would be to mate with someone who'd accept me for who I am, without trying to control or change me. Both one of my closest friends and an ASD specialist told me that they would recommend someone who'd 'wear the pants', but I really wouldn't tolerate if someone tried to control me against the policies that I acquired during my upbringing, or shortly, against my will. Even without that I'd feel so much hard-pressed that I could barely tolerate in the long run. So there's a possible antagonism that wouldn't make things easier for me.
I've given up on internet dating for the time being, and as a pathetic effort I plan to put up an ad in a local weekly women's magazine's L&D section, explicitly stating among other things that I'm mildly autistic...
