I'm confused

So i shave to the best of my ability down there. Well my bf has made some comments and i'm not sure what he means he goes "you shaved a little" i always do and it all neat but i don't get what he means. I'm waiting until next time to ask. Its hard when its all the way under but i try. Does he mean cause its stubble cause its usually a few hours after?? Anyone got an idea?
