Shave.... maybe he waxes or something

The first thing that came to my mind was "maybe he just doesn't produce enough testosterone to grow hair under his arms..."

Then I slapped myself.

Idk but when i get my own bb, imma force him to shave. maybe its just me .-.

I find it weird when guys shave their armpits, maybe it's just me, though >_<

YOU JUST FOUND THIS OUT ?? Mostly all Kpop artist shave. Not all the time but mostly when they do MV's or big important concerts or TV shows.
