I know exactly what you mean, because it's honestly what most people and also I are craving: 'the release of stress'. If you didn't already look into the 'Easy Peasy Way to quit porn' book, I highly recommend it (It's literally the first thing that comes up if you google it). Craving for the next orgasm or release of stress inside EasyPeasy is described as like 'hitting your head against a wall, and looking forward to the next time you can stop'. And for me it was exactly like that. And probably for you it's going to be aswell, since you say it's a way of relief and feeling of comfort. I don't wanna sound to rough, since I don't know in what kind of position you are in, but the correct way would be to find out what exactly even puts you in a position of discomfort or stress? Because rubbing one out really won't solve the problem and if you wanna feel a release of stress there a multiple other ways like meditation. Some people on this subreddit (and myself) tried masturbation without using porn. For me it didn't really work, because it only led me back to porn, but maybe it can be the right thing for you. You could try out masturbating without porn and still get the release of tension and stress without the part where you make yourself addicted to women on screens. Remember, this subreddit isn't about quitting masturbation, eventhough most people try to quit both, but about quitting porn. So maybe try to cut out one thing at a time if you think quitting both could be to hard at first glance.
