This hand is bugging me

[prairieboy]

Live 3-6-12 game at Harrah's in Lake Charles LA.

Loose passive table with only a couple of good players. I'm on the button with A [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/heart.gif[/img], 5 limpers to me and I raise. BB calls and all the limpers call.

Flop is K [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/club.gif[/img]

Everyone checks to the cutoff who bets. I'm a bit miffed that the cutoff bet into me and I'm also a bit stuck on what to do next. I just call, but am very torn between calling and raising.

Turn is the K [img]/images/graemlins/spade.gif[/img]

First player checks, cutoff bets and I call again as does the other player.

River is 3 [img]/images/graemlins/diamond.gif[/img]

First player checks, cutoff bets, I fold.

Could I have taken this pot by being more agressive? Should I have raised the flop/turn or was the cutoff in it for the duration?
