Everyone who has posed for me over the years is my friend. When someone approaches me to pose, I explain that they need to think about their comfort level as far as nudity is concerned. I also explain that I need what I call "nude mug shots": simple, plain shots of their face and body including any scars, piercing or tattoos they may have. We then begin a dialog, usually via email, then by phone and finally in person. Once I feel comfortable with them, and they with me, I put them in my “use” file.
