Blind steal, turn decision

[Marquis]

Villain in this hand is loose preflop, and I haven't seen any aggression out of him postflop in the couple orbits I've played with him. My table image is pretty stellar at this point.

Hero openraises K5o OTB. Just the BB calls.

Flop (4.5SB): 2 3 3r

Villain checks, Hero bets, Villain raises, Hero calls.

Turn (4.25BB) A

Villain bets, Hero ?

How many outs do I have on the turn? Can I call?
