Sexual compatibility is a delicate thing that involves chemistry, pheromones, shapes and sizes of the body, and differing sexual styles and ideas about what sex is and should be. For these reasons, I believe (for ME) that it was better not to wait. Sexual intimacy in a marriage is FAR too important to leave to chance. I don't want to be stuck with someone for the rest of my life who is not sexually compatible with me... and no, this does not mean that I slept around a lot.
But I do have a great deal of respect for those who make the decision to wait and then stick to that commitment. Good for them, if that's what they want.
