One word. Don't do it. That is the only safe option as you are a female, and that changes it completely. A male would not likely face the harassment, and constant begging for nude pics that a female would. While there have been females who post on here, and I will say that most of the males are respectful, but it only takes a few to turn it into a nightmare for you. In the internet age, there is only one safe option and that is not post your pic at all. Use an avatar, or as you have cleverly done, obscure part of the face as to still hide your identity. If you later develop a friendship with someone on the site and feel comfortable sharing a photo privately with them, that would be the way to go.
Just my thoughts.
