Meditate regularly
With meditation you gain immense mental strength. Meditation gives you  power to choose your thoughts. You can reject or accept a certain  thought at your will. This strength may be used in rejecting the  specific thoughts that motivate lust. With meditation you can attain a  satisfaction in greater degree. You control your own mind and thus  control everything within and without. 
Be less self centered
The sensation of lust is a highly selfish thought. It is a search of  pleasure without being actually concerned about others. Lust can be  defeated by a superior sense of love and philanthropy. Be kind and  generous and give love a priority over lust. Learn to respect the  opposite sex as human beings. 
Look into the near future
Use your foresight and imagination. What are you going to get from  lust? Probably it’s some kind of excitement and momentary pleasure. Try  to feel the satisfaction without getting involved physically. Project  yourself into the state after everything is over. Project yourself into  the state of relaxation and comfort omitting the intermediate stage of  physical involvement. The sense of well being that you intend to gain  through this involvement can also be gained without active involvement.  Fast forward your mind to reach this state. 
Look into the distant future
Identify the object of obsession and imagine what his or her body will  look like after 20 – 30 years. Imagine the wrinkled, feeble and  disfigured body. This is the ultimate stage where everyone must reach.  Do you still feel the same level of attraction? Looking into the future  helps one identifying the ultimate reality. May be its unacceptable, but  it is true. Face it and the lust will vaporize almost immediately. 
Identify the camouflage
Appearance can be deceptive. Read the mind. Understand the intentions.  Appearances may be seductive but it’s only a camouflage. Should such an  unreliable thing influence your decision? If we find an appearance  attractive, shouldn’t we be looking for more information before doing  anything foolish? 
Go beyond appearance
Within the physical framework of every man and woman there are organs,  glands, muscles, bones, mucus etc. The things that arouse lust are the  same things that are otherwise abominable. You would probably throw up  if you had seen the organs immersed in chemicals and kept in jars. The  things you are attracted to are glands and excretory organs. Are you  ready to make love with those glands and organs? 
Let go of the possessiveness
Lust is motivated by a sudden urge to possess anything we find  attractive.
 Lust can be outwitted with realization of truth. As long as  we will fall for the appearance we will be deceived. Sometimes we need  not to possess things. We may find Eiffel Tower  beautiful, but it will be a foolery to try to own it.
