While scrolling down your phone you accidentally come across hot half naked girl pics post on instagram .Then your mind react.. you lust, then masturbation thoughts attacks you. You have to program your mind in such a way that when you see those triggers u get annoyed .Interrogate yourself like: .She's hot, then what? .Why she's posting filthy pics? .Where are her morals? .What she's trying to achieve ? .How will feel if she was my sister? .Then what should do about them, and why? Ask yourself those questions, automatically you will get annoyed ,irritated by those triggers. If you do this you won't even want to take a look at erotic things. Do the same about porn.Is the mostly effective way to stop PMO.
