i'm too like to abuse the high sometimes, why not take advantage of that pesky libido? this doesn't make you not asexual.

but addiction is no bueno. The steps to get rid of it are simple, consistency is key.

1. Note how often you engage in your addiction, what kind of content you use.
2. Make plan/schedule where you gradually reduce the amount of time being spend on masturbation (depending on what your situation is rn - limit the amount to once a day maybe, then to less then seven times a week etc.)
3. use less hardcore content - porn tends to mess with people's perception about how things supposed to look and to be. hentai stuff counts as ultra hardcore, all of it. return to healthy realism so to say.
4. get new hobbies, something else to enjoy (not drugs pls). spend more time outside - a walk in the park can't hurt.

getting rid of any sort of addiction tends to improve a lot of mental stuff. but people struggle with finding hobbies and doing healthy stuff.
