I can't think of any sensory issues... other than the fact that I took to photography really well.

I was wondering about the interest/obsession thing. My understanding is that people with ASD had a single topic of obsession for a lifetime. But I could be misunderstanding this. As to socialization... it seems like this has become more of a problem as an adult. I had lots of friends in elementary and high school as well... even though a bit quiet I was always in the 'in-crowd' .. if that makes sense. Sounds kind of snotty though.
