>>21466755Japanese smut artists back in the day wanted to circumvent a section in their Constituation that forbid them from depicting pubic hair as it was considered 'obscene'. So they opted to draw younger women/girls since they hadn't grown in pubes, and since their main market was school-aged boys it wasn't seen as much of a problem. This would eventually lead to said young men developing a fondness for those younger characters. That developed into lolita complex which is still prominent in otaku culture to this day.
