I fought this and lost for two years. Mental tricks are limited...diet and exercise only helps to a point.
Here is my perfect solution. Don't dismiss it right away because I agree it is a bit odd, however it works flawlessly and is completely harmless.
Cover the shaft of your flaccid penis with tape. There ya go. but wait...there's more.
It can be scotch tape or duct tape. Wrap it around the entire shaft of your penis leaving some room at the tip so you can still pee. Make sure you aren't cutting off any circulation while the penis isn't erect. The scotch tape will last a little more than one day and the duct tape will last multiple days. It's completely harmless, completely painless, cheap, and it gives you absolute control over your sexual desire.
While the tape is on you might get the urge to masturbate at first but I don't even get the urge anymore while the tape is on because I know I won't be able to masturbate with it on anyway. Also the tape inhibits erections which makes sexual pleasure almost impossible. Since it doesn't cause any lasting affect on your penis, sex drive, or anything you can regain your sexual desire whenever you want.
Feel free to message me for more info. I know many other methods like what foods to eat and what exercises to do if this particular one isn't to your liking.

How to stop
I have found that wearing a male chastity device such as the cb3000 helps in prevention of masturbation and the loss of semen.
I have a question and I will also post it elsewhere if I can: How does excessive masturbation as a youngster (teenager) impact sexual performance as a middle aged man?
I masturbated excessively as a teen and should I be restricting my ejaculations even MORE as an adult because of this?
