Find a girl that s the only solution, the girl can be your life partner or just a partner to have sex alone for money or anything in favour to her.Don't worry it will eventually change once you find a girl and sex with her in real.
This is also one of the solution that I would give to OP or better find something to keep yourself busy and out of lust.
Try to avoid anything that would waken your lust or give you an urge to masturbate although it would be hard if you already watch too much porn I think everything would give you an idea or something to remember about porn.
