The solution to this problem is with you but let me tell u some things that need to be reminded to deal with this problem....
Life is much bigger and broader than we think of it.
Realise that by watching porn u r not only wasting your time and money but also helping those porn freaks earn money in any easy manner. You know in this world where billions of people don't even get the food that they need alongwith the basic things of life.
Life has far much better things to experience than this.
Not only frustation, u will develop many problems bcoz of this in ur real life. ur expectations and attitude will be affected. ur real life may be disturbed as ur mind would always revolve about such things....Go on live ur life....there is so much to do rather than watching porn.....You can join some hobby classes or some other activities that suits u. u can join a library n spend ur time there... BUT ultimately the decision will be urs. ur determination can only change it....suppose u take decision to learn dance then immidiately go n join the dance class.....one thing that is far more important than even joining ur interests is to remind ur mind that u r feeling much better in ur new activities, in ur new life.......Let ur mind feel it n get involved in different environment.....u will start enjoying. So u only need to take one decision. u will be blessed.
yeah one more thing u can discuss this problem with anyone who is closer to you. I mean who can understand u n can also help u out.
