God put us here to go through this kind of mental gymnastics, and He certainly put us here to enjoy our sexual lives. He put us here to ask, to try and find out the best way possible to live with our neighbors.

How necessary it is to cultivate a spirit of joy. It is a psychological truth that the physical acts of reverence and devotion make one feel devout. The courteous gesture increases one's respect for others. To act lovingly is to begin to feel loving, and certainly to act joyfully brings joy to others which in turn makes one feel joyful. I believe we are called to the duty of delight.
