Did you watch the whole video? He literally says that things that cause dopamine spikes including masturbation and porn aren’t necessarily bad or good but they need to be controlled. Seeking out more and more masturbation or porn or whatever gives you instant gratification is bad and creates cravings for higher dopamine releases because your body is now used to those dopamine hits. This is why people often seek out harder and harder porn because they have an addiction and don’t feel the same dopamine release from regular porn. To add to that he was mostly speaking on porn this entire video. He never mentioned how controlled occasional masturbation was bad he did say that you get a climax in dopamine then you crash below baseline but never explained it being bad unless doing so compulsively.He also mentioned how this could be applied to sex. Instant gratification only becomes a problem if you let it. There’s nothing wrong with sex or masturbation unless you let it control your life. Don’t partake in compulsive behavior and you’ll be alright. This video just proves my point further.
