I'll work up a detailed review over the weekend. Didn't want to spend the time to really write something good if no one was going to read it. I'll definitely touch on the general fit of women's thongs in it as well. To quickly answer your question though you want to go with medium or large depending on how the thong looks. I am a little bigger waist than you and that's what I do. To start out I would recommend doing a sporty (i.e.: stretch) women's thong and Branch out from there.
