Oh, wow, I have some ideas for you. Right now, the point of her writing assignments is to get her confident about writing.

Until she gets comfortable with these assignments, you should have her write things where there is no real need for her own opinion. Descriptive stuff. She can add her opinions but they are not required. This will help her find her voice.

1. "Caress the detail, the divine detail." Vladimir Nabokov

Have her sit down with a mirror and really look at her vagina. She has to describe every detail of it to you. I think this would be wonderful because I think a lot of women don't ever really look at themselves there. Men have such amazing relationships with their penises that we don't usually have with our vaginas. A minimum word count would probably help with this.

2. Show her a picture, some erotic picture and have her write about it. She can write anything she wants but she has to do it with her left hand (unless she is left handed in which case she has to use her right hand). Disregard if she is ambidexterous.

3. She has to write something erotic. But, she has to walk through the alphabet as she does it. "As Bob careened down Elgin freeway, gulls hovered in....." Like that. She won't have the energy to think about what she is writing, it's so difficult to follow the rules.

These are the sorts of assignments that demolish the kind of obsessive self-criticism that paralyzes you as a writer. Get her out of that habit and you can give her more meaningful assignments.
