1) Masturbation is completely normal.
2)
If you give up masturbation (only once a month), it is easy to get aseptic prostatitis.
3) You can make a preliminary plan. Control masturbation no more than three times a week. It will be enough to gradually control it to no more than twice a week. You can't quit masturbation. If you quit completely, it will definitely affect your body and development.
4) I started masturbating from 10 years old (the third grade of primary school) and now I am 28 years old. Masturbate once a day or two on average, up to five times a day. The whole process lasts for five hours, and of course there is a rest. Everything is normal now, and people seem to say that I am only 25 years old. And speed and strength are not bad (I have practiced Taekwondo).
5) This is very important. It is to use sleep time (more than 6 hours) to rest after masturbation. Otherwise, the spirit will definitely be bad that day, hurting the brain. Remember. Never masturbate until 2 or 3 o'clock in the evening, and then get up at 7 o'clock to go to work or school, which is very harmful to the brain.
