Here are my additional tips for POISers:
a) never orgasm in hostile/chaotic place. Schedule orgasm (masturbation, sex) where you will feel relaxed and stressless afterwards with loving people
b) take some time. When masturbating do it for 15 minutes, slow very slow. Same goes for sex. You can go faster after 15 minutes
c) work out, eat healthy food. yoga is also good.
d) Contemplate on shame and guilt and if you feel any try to work on it. Try to live a life where sex doesnt produce guilt.
e) be here NOW. Don't schedule things in distant future. Only do things under your nose. (To avoid stress)
f) Do what you love only. Focus on spiritual life (I recommend Krishnamurti, Alan Watts, Henry Miller and etc)
Good Luck. I'm feeling better bros. I've had rough years beacause of POIS. Good Luck. I know you can beat this
