Do guys like girls that are a little bad or what?
Some guys do. I know I do.
A girl who's got a little mischievous streak in her sense of humor, someone who doesn't have to be serious and perfect all the time, that's great. That doesn't mean she has to have multicoloured-hair and a thousand piercings and talk like a sailor; that's well beyond a little bad.
A "little bad in a good woman" is (for me):
--wanting to find a deserted curvy road, put the top down, and drive a little crazy for a while with me
--once in a while, dressing slightly immodestly for MY benefit (not for others), someplace dark, like the symphony or movies
--takes full advantage of a Cheat Day and orders a stack of bacon AND a ludicrous dessert
--is not afraid to communicate clearly and fearlessly to her husband when she is in a state of desire and wants her needs met
--says things like, "let's drive to the beach this weekend," spontaneously when the mood strikes her
--is not ashamed or appalled to receive and give affectionate touches from/to her husband in public (not talking outright groping, hands-in-clothes stuff...more like arm-around the waist, standing-spoons when in line at the movies or the like)
Little things that would make Puritans and Quakers rage, but the types of things that really, to me, seem healthy and normal in a happy, content marriage. I dunno, I could be wrong...happened before, bound to happen again. But Lord knows I would certainly welcome these sorts of little things from a good, God-fearing, Christian wife, because these things would be reserved for the two of us. The subtle bad streak is for us, and us only.
