Hello, I was wondering if people here have personal experience with mantak chias testicle breathing exercise as described in his book "Taoist secrets of sexual love". I was wondering if it is possible to learn this method based entirely on that book? Also I have questions regarding the methods safety, as I have seen on the internet some people warning others about dangers of attempting methods that manipulate sexual energy if one is unexperienced in this area or has no "master" to guide him irl. I am on day 50+ on my nofap journey (with a handful of P peeks during the time admittadly :/) and have been practicing this method for a few weeks, to the point where I believe I can guide the energy to my tailbone area. However the extra sensation and "activation" of my testicles during and after the breathing sometimes is very challenging to handle for the rest of the day, as I am not yet skilled enough to perform the entire method and guide it further upward. I know there is a few people knowledgable in this stuff here and would be very greatful for any answers. Cheers!
