I am not a very good player against the sicillian defense, and am wondering where i could have played better, especially in the beginning. after that i know i made mistakes.

8Bb5 was not a great move, 8f3 is the standard dragon line intending Qd2, and 0.0.0. Lots of theory there. 8...a6 was a worse response, you have options tonydal suggested later, and what played in game was ok too. 8...Bd7 was better, then BB5 just a tempo waste.

22. g3 it probably preparing f4 yes?

22. Be3 might have been better.

Black's dark squared bishop is currently on a very good diagonal.  

When black gets his bishop to  d4 it's on a very active square. Be3 stops that without black first supporting the move.

 The issues you have are your hanging pawn on the half open c-file and the open a-file which black can, and does, use to get his rook round.  Perhaps working your rook to c2 and your king upto g2

I think 8. Bb5 is where you pretty much lost the game, it wasn't a smart move from the beginning, as there was not much to be accomplished there.   It led to your bishop being taken with no answer, and allowed the black queen to dominate queenside of the board and wreak havoc.

 If anything, after 8... a6, you should have just 9. BxC6+, you could have minized damage by forcing a bishop/knight trade.  And after 9....bxc6, you could have gone 10. Nxc6, threatening black's queen and come out a pawn ahead even.

 Seemed like you were way too eager in the late and middle stages to force trades as well, and gave up position too much.  Black capitalized

All of these lines see you emerge a minor peice to the good at least
