Here’s a trick I used to use when I first tried to stop cooming. Whenever you feel any urges, just go and boil a kettle of water. Once it finishes boiling, grab the sides of the kettle and keep your hands there until you can’t take the pain anymore. The pain gets rid of the horniness real quick and even if you still have the urge to coom, your hands will be in too much pain to grip your dick
