As you can read in my profile I underwent voluntary chemical castration for more than two years because of my masturbation addiction (read more there). It was the only way to stop my bad behaviour as I also had really bad sexual thoughts (including to sexually dominate boys younger than me, but, of course I never did that) and imaginations. It is not nice and neither cheap to undergo this medical treatment, but over two years of chemical chastity made it that I got rid of my bad habits. At the beginning of the therapy it will take about six weeks until any kind of masturbation will become totally impossible. The worst period after those six weeks is the following three months when you have the extreme wish to masturbate, but you cannot. Very slowly you will forget that wish. In my case it took almost a year. But I continued for another year, which turned out as a really good idea. I am posting this because of two reasons: Is there anyone here with a similar experience? - And in case someone has questions about this I am ready to help.
