Suggest me books for a exposition therapy i am trying to do (i really wanna appreciate great stories with sexual content and i really l need to be comfortable with sex)

I am finally doing a therapy and i am seriously considering reading action books and fantasy books with something that i really want to be fine with that is romance about couples and also sexual tension and sex scenes, what happens is that i am trying to understand that romance and sex is good for a movie plot and it is also what makes good characters many times and i need to understand it, but the OCD thoughts really hurt me, just suggest me the book while i keep doing the therapy
