Yes... Most attractive (ie, hot) girls don't have to respect people, so they don't.
I think a dream girl could exist... If by dream you don't mean perfect. It's probably not what you think, or found in the places you are looking. And it can't be based off infatuation / lust. You're not going to find a hot skanky wild girl with a nice girl personality, character, and mentality. Sacrifices have to be made, but most people want hot, sexy, exciting, and sweet + other good qualities. They might view it that way during infatuation, but it's not reality. Lust is blinding, and hot girls know this.
