Cities are lonely. Philadelphia is no exception. Maybe you want to do something about it?
Maybe, alone with the night, passing under silent, blacked-out townhouse windows in certain parts of Center City, aching for companionship, for the illusion of a relationship, for someone to slap on some long black latex gloves and fill the holes in your soul, you discreetly turn some money into a few hours with a beautiful person experienced at keeping the darkness away.
Or maybe you want hard, quick, raw sex.
