From what I saw of those games you ARE getting your piecs behind his pawn rushes, you just lacked the bravery to follow up your attacks and began retreating.
Game 1 you castled right into a pawn storm - that was a definate example of when to delay castling. Also if he didnt play bc3 at the end it was a drawn game.
Game 2 - you missed mate in one for two moves running - Qe1#
Game 3, lasted a bit longer - this one was a more tricky position, I have had troubles with that sort of position but I generally try and break their stranglehold as soon as possible, before the attack gets dangerous. You left it too late here.
From these games what I can reccomend is a simple plan which you should find helps your game.
Try and play e5 or d5 in a game as black - if you set your mind to playing those moves and prepare them, you will find you have less to worry about on the flanks with the centre open.
