then you should have said straight away you don't like me asking that question! If you're not comfortable answering it then that's up to you. However, you can't really then get offended if, having refused to answer the question, people make assumptions one way or the other.
Oh and see what you're doing there, you little rascal, but no, I'd be more than happy to say if I were gay,in fact I'd probably be the type to come out publicly if I were a celeb, but I'm not a celeb nor am I gay, nor have I ever actually pondered whether I am coming to think of it. You could have just asked me out right!
