The Bible often speaks of the comeliness of certain women. Sarah, Rachel, and Rebekah were all noted as beautiful women. Nothing wrong with seeking an attractive, trim woman. But... you have to live with them the other 23+ hours of the day and that initial Hallmark-movie excitement will fade. Characteristics to definitely look for: feminine, self-controlled, trustworthy. After being married 20 years, I see these flaky chicks and harpies and I don't care how "hot" they are, they would be insufferable in a marriage. If you're thinking "what am I going to do when we've been married 15 years and she doesn't look as good as she did when we met... what if I lose attraction for her." Even as she ages with you and isn't how she looked when younger, her femininity will remain a key "stimulant." There's also a certain comfort that comes from just being with someone you know well, who's been through those battles with you over the years.
