Looks matter?

I was talking to a girl some weeks back on a chat room where the conversation headed to our relationship statuses and I am committed and I don’t really remember what her status was but one thing that she asked thereafter, startled me. She asked me, ”How does your girlfriend look?”. Frankly speaking this is a very common question and most asked when you tell someone you’re committed but I don’t understand why. Why does it matter how a person looks? Would you only like people who are pretty/handsome and cute and not care about how they are as a person and how they would treat you and how you both would connect (or not) ? Are these things totally immaterial against how HOT the person is? Also here I would like to mention how HOT as an expression sounds totally vulgar as against PRETTY.
This also raises the question about love at first SIGHT, is it possible? Is it realistic? Just by looking at the person for the FIRST time are you able to judge how a person would be? I certainly think this isn’t possible. You cannot know a person completely even if you spend your life with them and here you’re talking how you LOVE a person just by looking at them for the very FIRST time. So stupid!
Although I do agree that all of us who claim that we don’t care about the looks of either ourselves or people we like/love are not totally saying the truth. We all care about it but would never agree that we do. We all have our phases of how we think we’re not pretty/handsome/cute/*other synonyms here* and those who don’t are either lying or are blondes. (Yes I don’t like blondes much!)
Also isn’t it possible that one person may not be cute in your view but might just be the cutest person alive in others’ view after all you know what they say, “Beauty lies in the eyes of the beholder”
That’s all I have to say.
Until the next thought in my head, Ciao.
Oh as always, comments are appreciated.
