Most delightful and satisfying?
Having someone you can (count on) through thick and thin to support your goals in life. (A cheerleader and soft place to fall)
Steady Companionship - travel, events, dinners, movies, walks, talks, or simply sitting in front of the fireplace.
Deep Physical Intimacy - When two people dedicate themselves to satisfying each other for life passionately and romantically.
Having all 3 of these traits in a marriage is "magic".
