Forced Boden's mate
Well, the Boden's mate is actually delivered by 2 bishops, but some similar motifs are present in your game.
This is "probably" most famous Boden's mate:
You are right, it isn't a classical Boden, but the mottif is present, IMHO. Any input about the game and my errors?
Well, as you say castling queenside wasn't a good idea. I would have initiated the attack on move 16 instead of castling at all, there is not much you can do to patch up your queen-side, I would try to give him something more to think about than taking your b pawn.
Well, my first thought is that you were seriously underdeveloped to start pawn storm.
5. ... h6 is unnecessary IMO, only 4th choice for 5th move (chessgames.com opening explorer):

I would probably go with 11. ...Rxh6 (with later Qg5, Ne7 ... ), ...Nxh6 puts the knight and the rook out of the game.
Declining a queen exchange wastes another tempo, while he places his queen perfectly for attack, You obviously never saw it coming, and he was begging you to castle queenside.
Castling quuenside was really a bad idea when so many attacking forces(and no defenders) are aiming there, truly a puzzle material.
Connecting the rooks at some moment with Ke7(or Kd7) would be a better idea, center was blocked and relativelly safe.
