This is a challenge to not watch any porn (or look at any sexually stimulating activities) for 120 days, as well as not masturbating. To stop with the pornography part, I am using K9 web protection - for windows or any computer, and setting it to safety mode, Mobicip - for iOS, and use that browser only by adding restrictions, as well as for Android. But for these, you want someone else to make the account for you, otherwise, you could just re-enter the password; if you have no one, you can make this huge password, write it on a peice of paper for registration, confirm everything, then rip it to shreds For the self-stimulating activity, I don't know of any useful technique other than, when the urge strikes, find an alternative activity. Also, to re-wire your brain, you could place a rubber band around your hand, and when the urge strikes, you flick the rubber band, triggering pain - external stimulus, and thus making you remember the pain each time. These are some of the methods I was planning on using, any suggestions?
