Yes, it hard to answer such a question for someone that we think (believe) to be a young teen..... but on the other hand, I also believe if they are asking they need an answer based on age appropriate understanding.

Based on my past..... if I was to have asked that question, at such a young age, it would have been more out of wanting to know what it was for it was being done to me, sexual abuse.

I would feel more comfortable answering this question if I knew a little more about the situation and the person asking it.
