If you saw a bunch of it and presumably are fine what does it matter then? Sure it might have been uncomfortable for a few days and you may not have understood right away but so what? That's almost every week as a kid. Seeing some titties is probably the least confusing.
Many uncles of friends (or fathers, who knows) had stacks of porn mags we knew where they were as 70s kids. When very young they were icky and after that we took them home. Who cares.
