I missed this one as well. Simply has to be eyes for me, partly as they are my business, also they really are the window to the soul.Mouths can lie, if you look closely enough, eyes never do.
The person also has to have an intellect so I can argue, I mean discuss things that interest me.I simply cannot bear it when people just agree with me,it seems condescending.They also need a sense of humour,particularly the ability to laugh at themselves.
However one of my other big turn ons, is the sight of slim wrists at the end of a shirt cuff, and long slim fingers. If a man is an Adonis look alike but has short stubby fingers, then I'm out the door.
I think that's why Heath seemed so perfect to me,he had amazing eyes, an obvious intellect and sensitivity, and those beautiful fingers with quite often some form of bracelet on his wrist.
