I think porn is mental filth and disgusting, a girl who watches that, I would never marry. Nor should any respectable guy.
As for your other points, as long as she didn’t act out on her fantasies than I think that’s fine.
Its probably good she has those, that means you will have a healthy sexual life.
But you know, personally I don’t like girls (for marriage that is) who are open about sex, like even if she has all that stuff on her mind, she should be shy and bashful. I mean she’s your wife, not some ***** from a night club that you will spend an hour with.
