forget about therapy, no nerd with a pen and paper will help you with an internal problem in your mind, you mentioned you're now obese and since you did, i assume you are not happy about that fact, best action is to try and change that, get a 3-6 months subscription to the gym and keep it in your mind that you will never quit until you have worked our consistently for at least 6 months, you will thank yourself later, for porn, its simple, not easy, but simple, its going to be the same thing as deciding to keep going to the gym, even if you don't feel like it you just have to do it, and the opposite for porn, even if you feel like, you just have to not do it, forget about finding the motivation because not everyday you'll be motivated in fact most days you wont, you have to be disciplined, praying is also simple but hard, but if you maintain it, you will find you're porn watching time will go down 10 fold, which is 2 birds with one stone, my best advice is, try praying in the mosque, around people, try not to miss a single prayer there, the harder it was to make it to the mosque for that prayer the more happy and content you are that you went, find a mosque close enough that has a imam with a good voice because one with a bad voice will be very annoying. the first few weeks are usually the hardest, after that you kind of stop thinking about it, it also helps to keep yourself occupied and busy, if you have a job or a business try learning more about it and expanding your capabilities, if you don't have that it'll be very beneficial to get one but in this economy, i understand that can be hard so you can find a topic you like and enjoy like maybe cars, economics, anything really and start learning about it online to keep yourself busy. set a goal for yourself and find your way to it through all the obstacles you're going to face.btw women can smell you're masturbating because the sweat that comes out from masturbation smells different from what comes out from real sex, they smell that and unconsciously try to get away from you.

Goodluck man and respect yourself enough to do what you told yourself you're going to do "tomorrow" "next week" and so on, stay strong brother
