James, take my word for it, as a man who has alternated between "plain" and "good looking" my whole adult life (depending on my commitment to excercize):
Good looks can only get you in the door quicker, but they can't seal the deal. Women are not men. Three things seal the deal with "marrying" women: stability, adoration (of the man for the woman) and a sense of humor.
Adore a girl and make her laugh consistently, and you will win her heart. At least that's what Mrs Piece tells me...
Oh, and good hygene...
That's it. You understand!! Woman don't really want anymore than men do. At least this one doesn't. Just a little loyalty and laughter. I'll bet you're happier than most men too.
Women just want to feel safe, secure, etc. Men want to throw themselves against the world...
