Know-How Exchange : Branding

I am launching an online directory service that caters to the adult market 23+. no gender or racial bias. It is exclusive to adult entertainment ranging from organisers of bachelorette parties right through to swingers clubs etc. It is an online advertising platform that allows a person to tastefully search for the ‘less ordinary’ or even ‘slightly risqué type of service or industry. I am struggling with branding and tagline. I was thinking along the route of Mild to Wild as a theme. Everyone has there own idea of what pleasure is to them and so I am looking at somehow incorporating it. It has to be fun, daring and bold while retaining class. Ideas would be most welcome
