Yoga considers sex to be a natural function, very helpful in a loving relationship and, of course, indispensable for the continuation of the human race on the earth. The sexual secretions contain the seeds of life, concentrated life force and nutrients. Once depletion in life force takes place, the vitality level and resistance to diseases will tend to diminish. In addition to this, Yoga helps in having controlled and joyful sexual life. Through different Yoga poses one can learn to control sexual activities. A complete branch of Yoga, called Kundalini Yoga, deals with harnessing the sexual power. Yoga postures and techniques explained in this module will enable one to get into meaningful relationships and enjoy sex and also helps in treating many problems related to sex and sexual behaviour.
