What can I do to a bail bondsman that is extorting me for sex?

I had to get a bail bondsman when I was arrested. When I was in jail the other women in their told me to use this certain one because if I didn't have enough money that he would let me work it out. I didn't quite understand that but now I do. I called him and he got me out 2 days later when I was allowed to make a phone call! Immediately he started telling me that he could make my charges go away if j did him sexual favors. He told me not to have anyone with me when I came to court because I was performing. This acts after court. He told me in the back seat of his car or in a motel. He really didn't care where just if I didn't want to go to prison I was gonna do this! I don't know what to do or what I can do to make this stop and also make him pay for what he has done to me and I am sure to lots of other women!
