My boyfriend and I are sixteen years apart, I'm 29 and he's 45. Our age difference hasn't been a problem in our relationship, and we've been together for nearly three and a half years.
We are both aspies, and our relationship is the longest that either of us has experienced. This is probably due to the fact that we are both on the spectrum, and are able to understand each other better than our former neurotypical partners were.
I don't think that age is as big of an influence on a relationship as other factors are, such as temperament and interests. If you are both compatible with each other, then give the relationship a try. I believe that chronological age is highly overrated as a categorization of a person.
