I read The Happy Hooker at that age. (She has sex with a dog) It didn't traumatize me or make me have a weird relationship with sex.
But I also had a copy of healthy sex information book - Dr. Ruth. So I would make sure she has access to a similar book.
I've just started getting back into reading/listening to romance books recently. Many contemporary romance books, especially the ones that aren't dark, are very focused on female pleasure and consent. At every part of the encounter, the MMC (male main character) will check in with the FMC (female main character) to make sure she still wants to continue.
The only thing I think you need to talk with DD about is how unrealistic the books can be:
-- not every guy has a giant dong,
-- not every woman can have O's with PIV,
-- IRL when a guy starts calling you "mine" and is possessive, it's a red flag,
--having great sex doesn't mean the person will make a great life partner.
There is a HUGE hockey sub genre. I hate sports, but I've read so many hockey romances LOL But the hockey players aren't stereotypical dumb jocks. They are very respectful of FMC (or other MMC, because gay hockey books are a thing). The one thing I don't like is Puck Bunnies. They try not to slut shame, but it is obvious that they will never be a love interest.
If you want more information about romance books, go to reddit/romancebooks. That would be a great place to ask a question like OP asked. Also, to find more information about how spicy a book is, go to
