Curious kid?

So I’m not sure where to post this but does anyone, specifically someone with a female/girl child, know how to maybe teach or tell their daughter not to bother themselves? I understand there’s curiosity and what not but how would I go about speaking on this.. my child just came up to me saying something “hurts” down there and I asked her what, she was kind of holding herself then she kinda showed me. I think she found her clitoris and was probably bothering it and obviously doesn’t understand it so probably thought it hurts. I know this is weird and probably uncomfortable for you reading this as it is for me writing it but I don’t know how to go about informing/teaching her to just not bother?? She’s 4 about to be 5 if that’s matters?
