Is it normal to want to impress men ill never meet

I can never go out of the house without dressing up, while i usually dont wear makeup or anything, this does entail that it takes a while for me to be confident about going out. When im out I have a horrible habit of always looking for guys my age. its almost as if Im an animal preening for another. its a habit I cant destroy. i tried pinching myself whenever the thought that he could be looking at me had appeared in my mind but no die. I feel stupid and materialistic.
