"donktastic" attempt to steal the Big Blind out of SB, ended up...

...pretty much handing over 4.5 Big Bets to the guy to my right.

CardSharpCook referred to my J9o made str8 fold to a raise on the Turn as "Donktastic," (lol) so
I feel obligated
to share some more donkness with you all to help you not make the same idiot moves as me.

How bad was this:
$5/10 Limit,
folded to me in SB with 33. I raise, BB calls.

Flop comes a 7 A 2 rainbow. I bet, BB calls.

Turn: 9. I bet, BB raises, I call down. He flips over AQo for a pair of As.

How bad does this suck? What's the correct way to play a hand like this
(w/ "showdown value" like an A or any ppk. pair?).
Since I suck so bad, should I
consider just folding these hands in the future? (if I'm going to just be throwing Big Bets around like that?) Thx.,
