The last step in your training to becoming a slut is being proud. A slut is proud to be a slut. She's worked hard to get to that level.
So in order for you to complete your training you need to show how proud you are of your new slutty self.
Post a personal ad on a free personals site. I recommend Craigslist. It's totally free and most importantly, totally anonymous. So you can post your ad and not worry about any of your kinky friends finding out.
