Chastity is not so much about sex as it is about reverence and respect. To be chaste is to experience in such a way as to be fully reverential and respectful. When this is done, when one is not chaste, then experience fragments and disintegrates the soul rather than builds it. Hence it is important to know that we can violate chastity as much by prematurity as by substance. Chastity is not just about what we experience, but also about when we experience it. An experience can be wrong simply because it is premature.
Thus, chastity is about waiting for the right moment for something, about living in tension and accepting incompleteness and inconsummation in life.
