Why is Arianne Martell so Eager to be Queen Consort?

[Bratchild]

I always took it that Arianne was fine with either Edmure or Willas more in the idea of picking a husband that would appeal to HER.Someone who is close to her age, reasonably attractive and interesting enough to be married to.

As for being Queen Consort,I think she was more intrigued with the idea or would be until she either gave it any real deep thought or would be living in the reality,(particularly if she were stuck in a purely broodmare/eye candy position.That and she'd have to stay faithful to her King or else her head could be taken.As Princess of Dorne,she could have some leeway if she took a consort,(and if it were another woman,I doubt Tully would mind too much).
