Nothing! She's yours ... I do respect a woman feelings.

One nice song pop up on my mind:

So take her home and hold her close, touch her where she feels it most, but be true
And when she's making love to you, she'll do what you want her to
Treat her good, treat her like you know you should
You may never find another girl like her

If in fact the lady is your fiance and not an internet derived image I would say that, in my opinion absolutely, show her the respect she deserves and NOT show her off to dirty voyeurs on a public website.
This lady will be your future wife, not some cheap whore or disposable object to exhibit like a trophy or Playboy centrespread.

Who's your "fiance", Dana*kitten? Yeah, rIght! Whatever!
