Real BDSM Photos Wanted

I am preparing for a new semester of presentations and classes on the realities of BDSM practice and relationships. I would greatly appreciate some photos that I can use that represent real BDSM people, relationships, and activities. I would prefer not to use images produced by the adult industry, but rather actual, real images and people. If faces are shown, I will cover them for anonymity. I would prefer a range of activities from mild/sensuous to extreme and a range of relationships from monogamous to poly with a range of orientations and genders. If you are willing to allow me access to your photos, please email them to me at Emily @ PositiveSexuality.org or give me permission to grab some from your homepage, Fetlife Profile, etc. Thank you.
