Boyfriend's [M21] mom strips him down....what?!?

so, my boyfriend is a wonderful man. however he told me that ever since he was young, to punish him his mom would always make him strip and wouldn't let him wear any fabric in order to humiliate him.

and this continued well into adulthood.

which in itself is a proper textbook abuse, i know.

but her mom would casually make him strip too, like giving him bath (last week) or taking his shorts to wash. 😭

is this weird or am i losing my mind (i am not being too conservative right? cause at the the end of the day she is still her mom and she can see him naked, maybe i find it weird cause i grew up in conservative household?)

i feel like since my babyboy grew up in that kind of environment he doesn't even know how weird it is (in case it is)

btw i asked him and no she doesn't sexually abuse him.
