I don't really read romance novels. I'd rather live them or watch something like "Under the Tuscan Sun."
But if I WERE to read such a book, I feel the more visual, less the perversion...I mean it's in there. You have to get from point A-B, but what I would read or be compelled to read would be something real. Something I'd like to bring into my imagination, during a quiet night at home by the fire or just that moment, I actually have to myself.
The more real, the better, details and all. Forget about how you say it. Just write it. Then go back or have someone else do it and get a perspective.
You (figurative) want something, if you're going to pay money for it, something that gives you an elevation you'd actually pay hard working dollars to alter what it is you're either lacking or wanting to overcome perhaps

As of now I'm listening to Nora Roberts - "Blue Dahlia" and a second part or series, anyway, called the "Black Rose" I think.
