Husband here, but my wife has had a few men who have wanted her to pose for them and while she started out keen, she pretty much pulled out before actually going to meet them (usually with me along for security). She was often keen and excited at first, but then got cold feet when it was time to leave. I think it was the uncertainty of what they would be like, if they had some hidden little rape dungeon or something, or more importantly for both of us, would they not edit out her face. Our rules are to keep her exhibitionist side purely anonymous and hidden from friends and family.
Early on, she would let strangers watch her during our nude picture sessions outdoors, or if they owned the prop such as a boat, nice car, nice house etc, was more than happy for them to watch. When they wanted some pics of their own, she just asked that they let her cover her face first and they can photograph whatever else they want. She would often honour their own requests to pose like this, or spread that or whatever as long as they didn't photograph her face. All too often people would still try to sneek full frontal shots with face clearly in the shot, and we found a few of her pictures from these sessions online. Since then, we both have steered away from strangers photographing her naked.
