Sex is powerful energy. If you try to suppress it, it will come out in the form of depression, or wet dreams or some other problem. You can convert this energy into mental energy which will strengthen your mind and body.
This conversion can be achieved by doing abdominal breathing. when ever your are tense with the sexual urge, close your eyes and do abdominal breathing. With in 10 breaths, your urge will be gone.Google abdominal breathing to know details. practice it number of times per day. Sometimes you may do masturbation if there is a very strong urge.Do not worry if you fail sometime to control the urge.You can learn more breathing exercise if you Google Breath and extended sexual orgasm.
