I remember I wrote my first story when I was 12. There were no sex, so don't worry. I gave it to read to my mother and to my friend. After my friend read it, her mother also read it - they both liked it. But my mother said "it's not good". So, I didn't write anything for over 15 years. But, if you feel like to write - you have to do it. So, I started to write again. And the result is - my first book "Stranger in the elevator".
Right now I'm working on my second book, so wish me luck.
