Can Someone Help Me Find the Right Person to Share My Secrets With?

This might sound like a silly question, but does anyone know what kind of people it’s safe to share my secrets with? I really want to do scenarios where I can’t free myself, but have someone come by after a certain time to unlock me. However, I don’t know many people and the whole BDSM world around it is somewhat taboo in my country, especially among my circle of friends. I’d prefer to tell a girl, but there are hardly any that close. I’m too scared of becoming an outcast if anyone finds out about my little secrets.
