AKo, straight, river decision

[SomethingClever]

1/2 game on Pokerroom.

I have AKo in middle position. One or two limpers, I raise. A few cold callers.

5 people see a flop of AQT, with two [img]/images/graemlins/heart.gif[/img]'s

BB bets out, fold, I raise, everyone folds except for BB.

Turn: offsuit J.

BB checks, I bet, BB calls.

River: 6 [img]/images/graemlins/heart.gif[/img]

BB bets.

I can't raise, can I? Also, should I have called the flop bet and raised a non-heart turn?

I like your line. There isn't much logic to folding or raising, on the river so call it is.
I like your flop play. I always like to see where I am on the flop and not on the river
