Read up on Nofap. It's mostly pseudo broscience Youtuber bullsh!t with little to no scientific evidence supporting its purported benefits. The only study suggesting such was an experiment done in China where there was a significant spike in testosterone levels when going a week without masturbating, after which testosterone levels then returned to normal.

Routine ejaculation has actual, proven benefits for prostate health and overall well-being. Long-term abstinence is actually linked to
decreased testosterone.
Excessive masturbation, especially to porn, can be harmful. Short periods of Nofap (4-7 days) can provide
short-term benefits, but going a year? Scientific evidence suggests it will do more harm than good. Relieving a natural urge is perfectly natural and healthy. Not relieving it is unnatural and unhealthy. You won't hold in your sh!t for more than a week, right?
