Caitlin Moran: 'Every few years, I reread How To Be A Woman and marvel at what I got wrong'

When the author wrote her 2011 bestseller, she assumed she was through the hard bit. Ten years later, she's still learning

One day, back in 2011, I was on the train going into central London, when a big group of 14-year-old girls ran up to me, like a gang of giggling meerkats, shouting, Are you - are you CAITLIN MORAN? You wrote How To Be A Woman? Oh, my God! We learned about masturbation from that! Dude, it's amazing! We've all started doing it now! We've formed a gang! At school! It's called wank club! And we come in every morning and say how many times we did it last night - and then high five each other! In the playground! Shouting Wank Club! Can we shake your hand?"

Well, if your wrists aren't already too tired - then, yes," I said.
