Annoying spot- flush card on turn multiway

[One Outer]

I had a couple strong hands tonight that ran into a flush card on the turn against multiple opponents, one in position and one OOP. I'm still not sure how to handle these and I think I'm bleeding bets by misplaying these spots. Depending on these opponent I've been b/c and c/c these turns (or in the case of being in position, given the free card, which I'm sure is yucky).

In this first hand all are typical loose passive except button. He seems taggish but he's only been at the table for 30 minutes or so.

Canterbury Park 6/12 full game

Hero is UTG with A[img]/images/graemlins/diamond.gif[/img] K[img]/images/graemlins/club.gif[/img]

Hero raises, UTG+1 calls, all fold to Button who calls, SB calls, BB calls

Flop (5 handed, 10.5 sb): K[img]/images/graemlins/spade.gif[/img] 8[img]/images/graemlins/spade.gif[/img] J[img]/images/graemlins/heart.gif[/img]

BB checks, Hero...

HJ in this hand is same taggish player from first hand. The rest are typical loose passive. UTG is notable because he is playing the majority of his hands.

I include the reads just in case some want to talk about the particular hand in question but I'm mostly looking for ideas about how to play these spots in general. I've thought about experimenting with bet/fold. Clearly these spots are often opponent dependent but I feel that I can come up with some good guidelines for this spot facing a field of two or more players who are mostly loose passive.
My concern is that anyone paying attention would invariably notice me b/fing a number of times and start trying to take advantage of that. Then I have to adjust to that. This is exhausting. Ideas?
