Staffy I do remember being a teen and I remember days where I definitely smelt horrible (kinda like fish) and it took me WAAAAY too long to understand the “smells like fish” jokes when talking about genitals.
I’ve always thought from that point on that if someone smells really, really bad, then it’s likely poor hygiene but in those situations now as someone who is in their 30s, I would now assume that person is really having a rough time, so a stinky foreskin or labia is the last of their issues.
