I want to ask this girl out, but she lives in Port Lincoln, while I live in Adelaide, I just don't know whether to wait till I see her in person (which won't be for at least 3 months cause I'm on holiday In America right now), or to ask her via Facebook or Skype. I also don't have a clue what to say when I do ask her cause I've never had a gf before. I'm 15 & 1/2 and she just turned 16 a week ago.

So basically what I'm asking is, which method should I use to ask her and what should I say?

PS: Please don't go telling me that it won't work, after all you never know
