Life Hacks/Billie's taboos and interests

Sexual history

Billie has been told since she was 3 that she was, in fact, a boy. She knows though that her privates look like a girl's privates, and that anyone who sees them will wind up thinking she is a girl immediately. She does not know what it is about her privates that will reveal this, or what a boy's privates are supposed to look like, all she knows is the warnings her dad has given her. Aside from this, most other information about sex has been intentionally hidden from Billie in order to keep her illusion from breaking.

Sexual Knowledge

The only thing that Billie knows in regards to anything to do with anything tangentially related to sex is that her privates look like a girl's privates and so she shouldn't let anyone see them.

• Knows where babies come from?: Hasn't even seen a pregnant woman, and if she asks about where babies come from she is told she doesn't need to know.

• Knows what male genitals look like?: She has heard the word "penis" before, and knows that boys have a penis and girls have a vagina, but she thinks what she has between her legs is a penis that somehow resembles a vagina. She has no idea what a real penis looks like. She has also never seen another girl's genitals either.
