For your info, it's actually easier to have true
friendship with guys after they have been rejected by me. Of
course I know the guy will be feeling hurt, insulted,
humiliated, angry after I have rejected them, but you know
what? I am able to "heal" them after I have rejected or
"hurted" them. I'm able to make them feel better and recover
from my rejection that easy, and that's why I can still keep
my male friends after I have rejected them.
In fact, guys make better friends to girls when they are not
after them...proven! 
You think every lady is like you? Able to "heal" the guys they
rejected? You are right to say most of the guys are timid, but some
ladies are timid too, and this is a cause for a vicious cycle.
Just imagine, a guy likes this girl. But both the guy and the
girl are shy and timid. Let's say one day the guy finally had the
courage to ask her out, but even if they did go out on a date, I
would bet the guy won't dare to ask because he knows the girl is
shy. And he's afraid that after being rejected, they can't even be
friends anymore because she's just too shy.
And if that shy girl is not like you, able to "heal" him, that's
it for their relationship even as friends if he was to ask her.
Morale of the story: Not everyone is like you, so
straightforward and honest. Most Singaporeans are timid and shy and
introvert in some ways. It's our characteristics, and of course I
know it's bad, and we should change.
Added: I think you've yet to see girls that are so WTF. Tell
them my true feelings for them, and they play MIA. You have to
weigh both sides, you can't put all the blame on the
guys.
