You only say that because of current social expectations and standards though, what you must remember is that 30 years ago porn was
way harder to access than it is now, we literally live in a culture, particularly in the west, which absolutely
adores porn. Sure, in the past, people will have still been into it, but there wasn't the same medium we have like today, if you wanted porn, you'd have to be well-off or able to afford a prostitute, and even then, like aforementioned: porn is
a lot worse in terms of the amount of dopamine released compared to actual sex.
You
should have the urge to have
sex with a hot girl, sure, but not to
fap. A quick anecdote which I read somewhere, I can't remember exactly, stated that during the French Revolution, soldiers used to masturbate in order to reduce battle stress, and in order to keep calm. Some soldiers which masturbated too much, became known as 'masturbation mad' or words to that effect, and they'd actually be kicked out (or more likely killed) of the French Army.
