Ah, so you are looking to quickly roleplay some prequel scenes?
Seems we are on the same page. It sounds like the mother, due to her instability and experiences, may be the main influence, telling her "what all men want," perhaps making sex out to be some horrible or incredibly sinful occurrence. Of course, to confuse the issue, she uses her own body overtly or discreetly in front of her daughter.
As for the father, lack of empathy seems likely, perhaps making her get a job at a young age, not listening to her problems and seeming apathetic toward her happiness in general. I've done bits of an RP like this where my main character was a friend of the girl, so done this kinda background discussion before.
