J.P.
well, my question to you is if you have asked her why she is doing it? I am wondering if maybe she is somewhat itchy??? It may not be a self gratification type of scenario. Maybe she has a yeast infection, or is not cleaning herself or wiping well and gets itchy....that is the only thing that I can think of that might be going on besides the other. Maybe you should ask her....... Good Luck - I wish I had some miracle advice to give, but this is the best I've got this time.....sorry ;0)
