I require two things in a potential partner: physical attractiveness and mental attractiveness, both to be judged on a case-by-case basis. However, regardless of attractiveness, I would also require a break from the "it's a mans job to initiate the relationship" mentality, because I've got about as much spine when it comes to talking to the opposite sex as a jellyfish. I've only been in one relationship, and she basically forced me to be the one to initiate it. I was physically ill from the stress, even knowing that she'd say yes. I've never been able to do it again. Feeling like you're going to throw up and pass out are rather good deterrents.
