Is it weird/rude to be shy?

I'm not the most outgoing person and some people make fun of me for being shy. I don't really like being center of attention (I know its crazy right!). Well today this cute, sweet guy asked me out and I blushed and got scared so I just kinda freaked out and hid. I didn't know what to do or say. I have never ever been put in that position. I didn't say anything rude to him but when I told this to my friends they said that I was being rude. Others just laughed at me. Can someone tell me what I did wrong and give me some advice?
