I can't say that I agree with somebody losing their virginity at 13, but its not my body, an I don't have to live with it.

If she is ok with it, then thats a good thing. If she's not ok with it, then thats between her, and GOD.

If she decides to discuss it with *ANYBODY ELSE*, then its up to them to listen, and not be judgemental. if she asks for advice, she isn't looking to be bashed, or approval, she will most likely be looking for a way to deal with it, or at the least, just be able to vent.
