Keep in mind that I never use this opening... 

4. ...h6 is useless, just one tempi lost.

7. ...Bh5 would be better but Bf5 isn't bad either, Bxf3 wouldn't be so good however, as you trade the bishop for a knight and he picks it up with the queen, which will then be in a good spot, threatening Qxb7, for example and attacking f7 as well.

9. ... Nc6, was premature, you should have played e6 before

11. ...exd5 kept you in the game and prevented the tripled (??) pawns, traded the weak d6 pawn, and you had very good play in the center afterwards.

 

Perhaps better is 7...Bh5, rather than 7...Bf5, to keep the pin.

The threat of White playing e6 is too strong.  Better would have been 9...e6 instead of 9...Nc6, allowing 10.e6! 

11...Nd5 is the losing move.  Better would have been 11...exd5 12.cxd5 Nb8 (or 12...Ne5 13.Nxe5 dxe5 14.Qg6+ Kd7 15.Qf5+ Ke8 16.Qh5+ Kd7 17.Qxe5 Kc8) 13.Qg6+ Kd7 14.Nd4 Qe8 and try to trade Queens

The checkmate could be avoid. After c5, instead of Nc8, play Qd7 and forced queens exchange. If Qg6+ Kd8. If c6 attacking the queen, b7xc6, d5xc6. The queen has not problem avoiding the attack. The game at this moment was even in pieces and pawns, well your position was not very good but there were not inmediate danger.

 But after Kd8, cxb6, and the knight is lost and the position is very awkward.

 I would go further and say that h6 hurts Black.

 

1.  It weakens g6, allowing diagonal pins on the f pawn once black castles

2.  It also weakens e6 because the f-pawn is now doing double-duty

3.  h6 becomes a target for White sacrifices to rip open the king's defenses.

4. Oh yeah, and it loses time.

 

Notice how White's entire attacking scheme makes use of the weaknesses of Black's 4th move. 

 

Now I see why 4...h6 isn't played by the masters. Thanks for the comments everybody :)

Lol, aggresive attack.
