How do i do this??? (i need conselhos about blue moon)

Ok, so I chose to read Blue Moon for a book report, and know it's really hard to wexplain cause i feel weird mentioning the whole they're-tryin-to-have-sex-but-they-cant part. How should I do it? Only the teacher will be leitura the part about the entire book, but that just makes it even mais uncomfortable. I'm scared that she'll think I'm too young for the book(i'm only in 6th grade) HELP!!!
