There are two women in every man's life. There's you...the beautiful, charming sex goddess he's in love with. And...you, the woman who scares the pants off him.

It's not that you're scary right now; it's that he's scared of what you could become once the honeymoon stage of your relationship passes and the serious commitment begins. What's behind the fright?

The Sex Will Stop

Deep down, every man worries that so far the sex has just been the means to trap him in the relationship. Once you've got him where you want him, you'll start withholding sex as punishment, or worse, pull the sexual rug out from under him completely.

You'll Let Yourself Go

To hear the guys say it, the first thing to get dropped (after the sex) is your attention to personal hygiene. You'll gain ten pounds, spend all your time in sweats, and stop shaving your legs.

You'll Turn Into His Mother

Men worry that after things get serious, all his cute little idiosyncrasies - like leaving the toilet seat up or never washing the dishes - will become annoying, and you'll start throwing out orders (or withholding sex!).

You'll Try to Change Him

After you've trained him to pick up after himself, your man starts fearing that his wardrobe, social circle, and career are next to be adjusted. His real fear isn't exactly change itself, it's that you'll change him from the free-spirited guy's guy he is into a sissy on short leash.
