I know some people like dumb and hott, but I can't do it.
Intelligence is a requirement for me. I'm not saying you have to discover cold fusion, but I need someone I can talk to.
Keep in mind that I'm speaking fairly generally.
I need someone to talk to. NEED. If they can't quickly, broadly, grasp concepts (like you said 'I'm not saying you have to discover cold fusion' - its not like I'm super educated anyway), then it can be a wash.
Maybe I could take it if his body is super hot and his heart is SUPER warm, and he's successful in several other ways. Intelligence isn't exactly a turn on for me, but more something I need in order to continue positive communications for the long term.
