dont think so, the proof is the numerous athletes and others doing full on retention, if sex still maintained energy levels then the greek athletes and everyone would continue engaging in sex but just abstain from masturbation. also it would be akin to arguing the food you eat has different physiological effects depending on whether you eat it yourself or have someone put the food in your mouth. only the psychological things change. i think Peat was referring strictly to masturbation vs sex, its possible he could have a different opinion if porn was involved but i dont know. many people feel depressed, or like losers, after masturbating.you really don't think there's a physiological difference between the two? they're drastically different. keep in mind peat was born in a time when televisions were just starting to get popular, it took many decades for internet porn and compulsive masturbation to even be a thing.
