I found it. Ashley speculates on her obsession with sex. From being molested by someone (she can’t remember who), to underage sex, to not wanting to go to the Woolzacks house, and others.
Among them, she admits to showers with her dad at a young age, and writes that it was probably not appropriate.
That’s what all the fuss has been over. I hope it was worth it!
