For me, physically it's long hair (I think that is SOOOO sexy on a man) and mentally it's shared interests. I'm not one of those people who could be in a relationship with someone I had very little in common with, no matter how nice a person they were I like having lots of topics of conversation.
I love a Renaissance Man! A scholar-athlete in school and in the adult world, someone who's at ease with people, optimistic, musically inclined, liberal and a gentleman.
