I think it's ok if you blur out their face. Personally, I would love to see their face, but their privacy must be protected.
Maybe like these pics? You could say it's Neela or Mila (sorry, only two I can think of with similar body to girl in pics) but no one can clearly see their faces.

Oh and make sure there's no tattoos or anything identifiable. I think Kraygee has already posted some girls he's been with...not sure if he had their permission though, but honestly, as long as you've done your best to protect them and you don't do it maliciously, I don't see a problem.
