This is where you are going to be incorrect. He literally thinks his novel is realistic and not fictional. He thinks that everything that happens in his novel is realistic. Many people have had conversations with him about this very topic with him. He holds true that it's realistic in his eyes. There is another example in that Jennifer scene that I won't bring up, but it has been a topic and I really don't want to go down that path again.
You do realize that sex with the males will most likely happen at the back end of the novel right? Because L&P believes that to be the ultimate sin in her relationship. So I would say if he's cutting this into roughly thirds, PD 24 -30 will be with the males. So besides her husband, all the males are going to have a long way to go. So strap in because if you're following Dylan, Sam, Zac, Aiden, or anyone else you're going to be on this ride for a while. The female cast will get the first crack at her. PD 19 is reserved probably for the female cast if you look at this outline.

The 2nd, 3th, 4th lesbian scene with an important cast memeber happen from this current PD 13 to PD 19. So If I had to guess PD 19 will most likely be either Sophia/Ellie or Sophia/Paticia at this point.
