One thing stands out immediately; too many pawn moves. 2...f6? in particular is a move you never should make.
Try to move just the two central pawns until you've got all of your pieces out, don't block the f3/f6 square for your king's knight, and try to castle earlier, behind a wall of three pawns 
I agree with theoretical boy. You're making a number of moves with pawns that don't really contribute much to the opening of the game and instead allow the opponent to mount momentum and pressure. It strikes me that you're trying to take control of the 4-5 ranks by advancing pawns early, but are over extending and allowing your opponent to take charge.
There's nothing wrong with you; it is your chess that is languishing.
1. try to castle... and not moving the pawn where you are castling...
2. don't advance so much the pawns, develop the rest of the pieces, the player that develop al his pieces first, usually has the advantage and win
3. think of your move, was you piece protecting something, and if i do the move, do i leave it unprotected (like most of the pawns on you 2nd game)
I think you may find the following video I created on January 3rd, 2009 to be of assistance.
It's titled: Basic Opening Ideas
I think using the 2 rules of thumb that I state in the video will help to improve your play.
Best Wishes...

Try to castle early, and don't move your king if there is another option, because then you can't castle anymore. In the first game, 10... Be7 is better I think, and 11... Bd7 is better to. By my opinion
Hey thanks for all the awnsers, i really appreciate it, I understood all the ideas and I am checking out both videos and undestanding all the concepts, and what about attacking from a flank and advance queenside's pawns to gain spacial advantage?
What about openings, what openings should i focus on?...
I've been learning some openings, but it goes on to a time that i Dont know what to do...
(I'm really shocked, I didn't think so many people would help me, thanks!! =D)
This is some of my games, and I'm failing GREATLY
