Sometimes I stack off on AK here cuz I suck.

yeah, usually doesn't end well. Only hand you can fold out here is TT or another AK.

How often has he been 3betting, especially from BU and IP? Has he ever flatted a 4B before?

If your not 4B bluffing enough, I would make my 4B size a little bigger in this hand.

fine, betting 32 and calling off is also fine

I actually like it better to bet 32 than your line I think, it's basically saying you're going allin regardless, but it looks less like an AK desperation move..

oh and if he shows up with jj/qq make a note that he flats 4bets with these hands instead of shoving because you will have to adjust your play in these spots if these are in his range.
