In what ways can the Kama Sutra improve serious relationships?

 For most couples, if they can get the sex right, the rest of their relationship problems can be worked out much more easily. This is because to get the sex right requires that they do their inner spiritual work to become fit for relationship, which simply means that they learn how to give and receive love. One of the primary ways lovers give and receive love is with sexual lovemaking. The Kama Sutra emphasizes the necessity for people to learn the art of lovemaking at an early age, preparing them for the life commitment of marriage. There is a great deal more to a relationship than sexual knowledge and skill, but without that sexual knowledge and skill, many find their passion dies and they lose interest in each other, turning their attentions to others outside of the primary relationship. Partly this is simply a matter of sheer boredom. Anyone who has learned and mastered the techniques taught in the Kama Sutra would never become a boring lover.
