It's surprising to learn that in the past, Japan had sexual customs that would now be considered criminal. Against the quiet of night, men would sneak into the bedrooms of women they desired, satisfying their lust with innocent recklessness. In the darkness, women would accept the hot semen of men whose identities they couldn't even discern, symbolizing a deeply rooted sexual pleasure within that era's society. During the time such customs existed, men could easily achieve sexual satisfaction. Social norms then were vastly different from today, and in some aspects, sexual relationships were treated with far greater freedom.
