I had to look up Otaku, lol, but I do know quite a few now that I know what it means. Not my generation; I don't get it; but I have met girls who definitely meet that description. I am sure that it is not impossible to find a girl who will be interested in the type of guy you describe yourself as. More important are going to be all the other soft skills involved with dating, so that you act appropriately in moving towards a relationship. I think that is actually the part which is most difficult for many Aspies.
