Emotional attraction?

Girls, is it true that you need to feel an emotional connection with a guy to become attracted to him or get you turned on? I've heard girls say that they can see a hot guy but just enjoy the view but not actually have any interest in dating him. I know that's not true with us guys Because as soon as see a cute or hot girl, we're jumping on that train to try to get her. If it is true, then how do you explain girls that have one night stands where there's no emotional connection really?
