I frequently sacrifice the queen, whether I intend to or not.
Did you ever sacrifice the queen ?

I did it once (unintentionally, of course) on the final game (knockout system) of the interclass tournament on highschool. Fortunately I already had a huge material advantage and a passed pawn...and after all, I won the game.
Regarding to the OP, great sacrifice! Those forced lines doesn't occur often and I would think a LOT before playing Qxg2+. I think I would probably go through this line:
@HilarioFJunior
Nice to hear about your queen sacrifice in otb chess. Cheers!
Here's a defensive queen sac in a game I just played.
Got a won position after that, but lost on time.

Right there with you lol!
Not the one I was looking for but still counts nevertheless:
The one I was looking for was one of my earlier online games. Funny thing is I didn't even play it with the expectation that they'd actually take the queen since the immediate mate was obvious. White played 1.e4,e5 2.f3? in that one.
I forgot that I recently also sac-ed a queen in a slow time control game.
Of course. Once for two knights without any clear-cut compensation against an NM, won on move 60, sacked on move 20.
And some only sacrifice the queen when they can calculate a #checkmate# in 3 or 4.
I hope to inspire you to put that fear, to not do it, in the fridge,
and be open to the courage to sacrifice material for that higher goal in chess, that enlightening moment :
To please the audience ... erhmmm, ahum, cough...
to go for a nice checkmate finish !
Here's one I just played, which filled me with joy.
