Chat room blackmailer

I am a male and I wear **, I chat on e-chat pretending to be a girl in her pantyguns and send pictures of me in them to others members hoping they don't mind seeing my 9incher in **!. Someone on e-chat found out who I was and found my facebook and address he is now blackmailing me to wear my pantyguns to work and take a picture or he will post my address all over e-chat! what do I do?
