For the fertility part, sure but... ...I get the feeling that Anna still hasn't grown up yet and I'm not convinced you can blame that on hormones. She wants to have lots of fun with fuckbois ('cause it's fun) but those guys make horrible life partners; they're just fun.
The guys who make great life partners (i.e., husband-fathers) aren't "fun" for Anna. If they are able to be bulls and studs then they will ( 'cause that's fun for them); they won't want to be bothered with "boring" family-guy things.
Anna wants both but I don't think she'll find it. Her beauty days are numbered, as she constantly laments and unless she finds a weak life partner (i.e., David) whom she can convince to allow her to hotwife, I don't think she ever will be completely satisfied.
