hahahaaha...this world is fucking messed-up :D.
Yes, I understand that they are doing it by internet. They just don't know how to get a woman. In their countries they are privated of free sexuality, so it's very hard for them to experience that.

What can we do against it? :) And now that you know that things are like that, what are you thinking to do? :O
