I'd prefer someone to be attracted to me based on my personality, or intelligence. Assuming the person is smart enough to put that over looks, you can probably hold intellectual conversations with them and be able to work through your problems easier.
Looks don't last forever, so they'd leave sooner or later. This question is a no-brainer.
Smarts first, looks second... as long as he's happy with both! But looks change over time, so if my mind and my intelligence turn him on, that gives us something to work with. If it's only my body that turns him on, the relationship would likely be short lived.
SMARTS!! i've always wanted someone to fall in love with my smarts. Because overtime my looks will fade but this brain (points to head) will always remain bright and witty. Plus, i don't want to be a trophy girlfriend... take care :)
