What can i do to break my masturbation/porn habit?

Big picture: If you're obsessed with erotica to the extent that it's interfering with your doing the things you need to be an effective adult, your physician can help you reprogram yourself. Otherwise, talk with someone sensible. You're keeping the pressure down, staying able to focus and enjoying yourself, and it's near-universal. Only an ideologue would say it will degrade your relations with others.

12 step and therapy: Hello, the way that I have seen patients overcome an addiction to porn is to join a twelve step group for sex addiction (e.g. Saa or sex-aholics anonymous or a faith based 12 step group called "celebrate recovery). The other component is to see a psychologist or other type of therapist to explore what the porn habit means. If it doesn't hurt you and people around you then maybe you don't need to?
