This is such a crock of ****. I'm in an autistic support group. Do you know how many of them (both male and female) have autism and are married with children? Even my son has had dates. And then, of course, the guy my cousin married.
Does it make you feel better to believe that autistic people "can't get dates" either? Sorry, try again. They can and they do. The only thing stopping most people with high functioning autism is themselves, just like any "normal" person. It's not about what damn disorders you have, it's about who you are and what you do!
It's really hard having relationships with aspies though, you have to be a confident and not overly sensitive person because you're going to deal with a lot of brutally honest bordering rude stuff, some very hard times making changes (routine wise or emotionally), anxiety attacks... I wouldn't recommend it for the faint of heart.
