Both, but more the extremes of both.
I like either extremely social butterfly like, extreme "NT" kinda girls, or I like girls, well, like me. Not always nerds, but more, if we're thinking in Meyers Brigg, the ISTP kinda girls. As far as neurological, well NVLD is sorta rare, but I think from what I've read from girls with NVLD, they seem to think most similar to me. So if I can find a girl with NVLD, it might be pretty cool, but it's rare to find people with NVLD. A girl with Aspergers might be OK, but it's still different from my NVLD, so yeah.
So yeah, either super bubbly hot NT girls, or I guess NVLD/Aspergers. I DO NOT want a girl, regardless of neurological or psychological profile, with extreme social anxiety that requires me to accompany her everywhere and do all the negotiating or whatever. I like a girl who does not need me to handle her affairs, and order for her when getting fast food or something weird like that, and constantly need my accompaniment whilst venturing out into dangerous places like Walmart. So in that sense, usually most extroverted NT girls are better at that, so yeah.
I don't know if that's really conclusive of a post, but yeah.
