So far I think attraction has to deal with the following: but who care's? I'm only 17
Physical Features: it's what you first see in a person and can be a first good or bad impression on a person
Personality: it's what you see next, they way they react to situations or certain things might intrigue or flat out disappoint you
Chemical: Can't explain this one but... it's just there to make the ride smoother or rough it up abit
Background: I believe culture has to do a lot in attraction as well, different beliefs or similar beliefs can attract each other and can be related to Personality
Skills, Talents: These are of course bonuses, but it can also lead to someone being attracted to another
correct me if i'm wrong =) Overall, I think every girl has 'SOMETHING' attractive about them
