I don't know. I always keep a pretty strict division between reality and fantasy (which gives fantasy more freedom), so I don't try to project from one to the other.
But Wendy Whoppers seems to have only the distainful/lifeless 'where's-my-cheque' persona even in hardcore scenes, and I don't imagine being very interested in her in person. For all I know, her body may be all she has to offer.
