Bec Paris has done the same thing, and we had to teach her she needed to be gentle with her body. She would wake up in the middle of the night screaming, I'm not sure what she did as I didn't examine closely but my understanding from what she explained she's rubbed it too much. So she and I had a chat about her body and she can do what she likes but she needs to be careful or she is going to hurt herself. I came to the realisation that it was my responsibility to teach her not to hurt herself because in any other situation we wouldn't let them do something without them knowing the consequences if it resulted in pain so I figure the same needs to apply here. And the other reason is because when she's woken up with a sore vagina at 3 am and screaming in pain I'd prefer to prevent that and get some sleep LOL! She knows her body is her own, but she just needs to be gentle.

I remember freaking out at first, but I know that its perfectly normal behaviour (even though it seems less socially acceptable for girls than it is for boys...) and I don't want to create all sorts of disfunction by making a big deal out of it or forbidding it (how hypocritical would that be LMAO!).
