I have that same problem! I don't think I ever held someone's gaze for more than 10 seconds.
It's almost as if you can feel someone reading your thoughts.
Well, that's how I tend to feel.
I'm quite paranoid.
And you must have the most amazing and understanding boyfriend ever. Any guy whose known me for that long usually has given up on trying to break me out of my shell.
It's kinda sad. Oh well.
