People took lolis back then because it guaranteed NO AIDS and such. It was pretty rational.
Also, with no 'beauty industry' and lots of manual work and so on, women aged even faster and in worse manner than today.
So it's just about choosing goods that are fresh, unused and healthy.
Considering the struggles of everyday life they faced, lolis were THE LEAST problem people had at those times.
The entire 'morality of a girl & man age gap couple' is a 'luxury belief' type of an 'issue'.
