It depends what you want to do. Porn is a definite no. It degrades women along with distorting the image of sex. If masturbating replaces sex, then definitely stop. If you are having sex and are happy, then it is up to you. What is healthy is ejaculation, not masturbation. It is good to let it out. Sometimes, you can't find sex, so you need to let it out somehow.
My Opinion I think that you should stop for at least 90 days. If you have a partner that you are having sex with, why do it? Not masturbating for a period of time really boosts your confidence, allows you to hold conversations and eye contact, and much more. I remember when I used to masturbate at least once a day, I would get boners constantly. I would always be horny for no reason. Ever since I stopped, this has not been a problem. Studies say masturbation is healthy because it is considered normal. So many people do it, it can't be considered abnormal.
Reality Quitting fapping is hard. No matter how long of a streak you are on, you can get horny completely randomly and ejaculate within seconds. I got the urge when I was working on homework in my room. 30 seconds later, I was feeling regret because I relapsed (fapped). The whole point of NoFap is to cure people of porn and masturbation addiction. They say that after 90 days of no fapping, porn, or even edging, your mind will reboot. I say that you should go 90 days without anything and then see what you want to do. At first, I was just like you. After finally reaching a week, my perspective totally changed. Try not tapping until you reach a week and then see if you want to go to 90 days, and then after that see if you want to continue.
Good luck to you in your journey on NoFap. Just remember that porn is bad no matter what and if you relapse, especially on a big streak, don't worry about it! Just forget about it and keep trying. The number of days is just a number. It does not matter. All that matters is that you are doing it. If you have any questions or concerns, feel free to ask. This community is here to help you.
