I can't imagine that there are no guys in Manila not wanting to even send you a flower or wherever they come from.
You are young, so don't lose hope.
Participate in the forums, go over the pictures, profiles, sometimes we ladies have to make the first move.
It's better to find a good partner, making a good choise than just go for the first that enchantes you. It takes time.
I have a couple of friends here that have made it and are very happy, surely you will be too.
