I'm 40 and my GP told me yesterday that it's highly likely that I have Asperger's. I've suspected as much since our son was diagnosed with the same in 2011. As we went through the enormous questionnaire the paediatrician was using as part of the diagnostic process, I'd be answering yes to many of the questions in regards to our son, and yes in my head in regards to myself. Things I'd never even realised were related to Asperger's were included in the questions. At the end of it he smiled at me and said, "YOU answered 'yes' to a lot of those, too, didn't you?"

So yeah, I had an inkling but it wasn't ever anything I pursued as there wasn't really any point.
