I always end up with IxFx types, easier attraction on both ends probably.
Appearance catches attention first, but then their personality also has to be more than acceptable.
First impressions count... for my presentation. I'm 99% of the time going to be less judgmental about first impression than she is.
Ideally her appearance of being pretty and interest-provoking would excite me enough to approach, but my 5/Ti always kicks in and goes "OKAY HOW TO DO THIS" and feels a need to have an effective opening line. I need to get better at just saying hi, and then rolling with the environment and conversation in real time, if I don't have one for the situation. (The best one I ever did included both good opener and good conversation flow, and led to a relationship, so it's worth something.)
