no, I shouldn't have to say "I have a boyfriend" (rant)

Once when a stranger at work asked me out I told him "aw thank you but I'm not emotionally available right now."

When my male coworker came by to ask how I ended it and I told him, he said it was very rude of me and not the way to do it. Another man in my life said the same thing. I asked them and a couple other men what the right way to answer is then, and their complete lack of a definitive answer made it very clear that the only right answer that doesn't make me Bad is apparently "yes".

(Yes, I did voice that last part. No, they did not like it. And no... They never did come up with "the right answer.")
