I'm pretty sure that cases of social anxiety are higher with aspies than NT's, so that might explain the lack of interest to form relationships. As far as desire, I think that we are the same as NT's, except that there are many who are in denial, and claim that they don't wan't sex or a relationship(excluding those who are truly asexual). It's easier to claim that you don't want something, if you know that the chances are slim of ever getting it. But, deep down, I believe that desire is still there somewhere.
