How to stop lusting after my attractive female friend?

Anonymous
Me and this girl have been friends for a long time now. I liked her from the start and told her my feelings, however she friend zoned me. We are still friends but I can stop lusting over her. Since I don't have any chance of romantic relationship with her, I strongly feel that I should stop lusting as it is harmful to our friendship. I have tried a lot of stuff but it doesn't work. Also she is a bit too comfortable with me and her being really touchy with me isn't helping the situation either.
What should I do?
