Hi Jen,
I bought my wife a photo shoot with a professional photographer last year. It wasn't exactly a boudoir theme, although my wife did some risqué lingerie shots and nude poses (with a strategically-placed silk sheet!) to push her boundaries.
My wife wasn't sure how she would react in front of the camera but, as it turned out, she relaxed quickly and produced some great poses. It helped a lot that we both "clicked" immediately with the photographer, who was friendly, down-to-earth, encouraging and respectful.
The outcome was that we have a set of photos in a little portfolio as a souvenir, and my wife has gained a lot of confidence from the experience. 
I'm not sure whether this answers any questions for you, but I hope that it gives you some encouragement that a proper photo shoot can be a worthwhile experience. The trick, of course, is to find a professional photographer who has the technical skills and the people skills to make you comfortable and get the best out of you.
