ok, good point...but my point that the scriptures teach us to overcome our lower, sexual natures still holds. We are supposed to need sex less and less, not more and more. That much is evident to anyone who is on the spiritual path.
While sex should not be what we strive for to make a good marriage, in a good marriage both partners will often strive for sex as an expression of love and joy for each other. Self-control and indulgence is switched around at the point of marriage. To engage before is indulgent, to abstain after is indulgent.
