I'm gay and I don't speak with a lisp, but I'm not camp either, I'm just a guy. I really hate the 'gay lisp' thing, especially seeing as it makes a straight kid's life harder if he has a lisp. I can, however, understand that it makes it a lot easier for people to identify that that person is gay. I've only ever seen it used by gay guys in the media who are portrayed as really camp...
