yeah just confess it. you should watch 'fei cheng wu rao' and 'bai li tiao yi' (check online or satellite) show to see how the guys deal with this. basically those that go on the show don't really care if they get rejected.
anyway i used to be shy, but not really anymore due to age increase naturally. however i might be more warm talkin to ppl i know close as hell in general (whether male or female).
