As the song goes..."a smart woman in a real short skirt, a smart woman who knows how to flirt, a smart woman with a mind of her own, a smart woman who wants to take me home..."
Also helps if she is sexually strong, sexually powerful, sexually confident, lusts for huge, knows she is a sexual being, and is insatiable...curves are very nice too. LOL But smart eyes that twinkle because she wants you and is going to do her best to be a spectacular and passionate lover is just simply the best.
