My Secret Life As A Prostitute is a blog by a woman who claims to be a real prostitute. Not the kind that stands in streetcorners but the kind that acquires clients by email and various "dating" websites.
She blogs almost every day and it's often very interesting to read. Some entries are just about how stupid men are, but a lot of entries are her answering questions from curious readers. So, if you've ever considered to become a prostitute, read her website first to get a feel for it.
