Hehe, that brought back a fond memory as I was never allowed to read it as a teenager. I remember when I was about 14 or 15, a new family moved into our culdesac and the daughter who was 2 year older than me and had Dolly magazines and I remember borrowing them from her.
My parents were protective and never talked about puberty, periods, sex etc. I learnt it all from friends and Dolly!
If you are open about these things already, I say go for it!
