Please tell me - is it a physical attribute you notice about a person that you are first attracted to, or is it a quality you get to know, admire and love, or is it, simply...chemistry? Are these separate aspects we notice at different stages, or are they sensed, measured and judged in the first instant? Please understand what I’m talking about: you know what you like in a girl or a guy – butt, eyes, smile, legs, mouth etc. – and that is what may attract you at first.
