Soccer (Football) advice?

I was thinking of starting soon, never played before... I'm almost 19 yrs, 58 kg and 170 cm, I think I'm quite fast and have good acceleration, though I'm not so good with the ball. (Yet) I have never really played a full game, so I don't know how I do defensively or attackingly, THOUGH, I think I would be a tad better at defending (or should I say worse at attacking?) but I partly contribute this to my lack of experience with the ball, ie. ball control and dribbles.

Which position do you think would be best for me? At first I thought of something like an attacking mf (Iniesta) or a winger like Messi, butt when I come to think about it I might be good as a full-back. They are often pretty small... or would I be too small you think?

All comments or help are appreciated! :)
