It may just be that she's young and inexperienced. Women, even more than men, tend to "grow into" their sexuality over time...as they get comfortable with their bodies and who they are as people, and as they stop spending so much time trying to please others.

You can bear with her, encourage her friendships with older women, and invest time in trying to help her explore her sexuality. However, the majority of the inspiration must come from within herself.
