What does it mean for you?
I think passion is :
you both laughing at something stupid
loving that face he makes when she eats anything green
you step wrong on the sidewalk and he always grabs you to make sure you don't fall
he's made you mad but gives you that smile and you're not quite as mad as you were before
him saying he loves you before he gets off the phone
he prays for you and your marriage to stay strong
and that his kisses are still good after years together
Of course great sex would be in there too, but it's not always going to be great.
