Do you raise this turn?

[pba08]

MP2 is 13/6/4.5 over 140 (small sample size). Table is quite loose-passive, with a bunch of hands where we had 4-5 to the flop w/o a raise. MP3 (lag) & I have been doing almost all the pre-flop raising.

This felt like a continuation bet, but I didn't want to play back with this many people in the pot.

Do you raise here? Calling would be horrible IMO. I think it's a raise or fold.
