I would recommend that you don't bother introducing yourself to any women online. Here is why,
1) Although some women are partial to having anonymous online friends, they will not appreciate your eventual romantic overtones. Facebook isn't a dating site, although in some rare occasions people have gotten together through facebook, its not going to happen when you've never met.
2) Its become something of a well known phenomenon that most men on the internet will eventually look for sexual content. Some men have no self control and/or are morally corrupted enough to con western women for their money. Cultures get stereotyped and men get vilified.
3) Unless you are using a dating website (thats whole purpose is to be used by men and women to contact men and women) online, you need to know that the internet cannot find you a love life.
Hope I wasn't too blunt there, but I cannot stand men making fools of themselves when it comes to women and online escapades. It makes my entire gender look bad and doesn't exactly dispell some well know stereotypes!
