Hmmm tricky. I guess I'm worried about being raised and want to see a river, so I might just check. That said I don't see anything wrong with betting here. Against one player i'd definitely bet, but the fact that you have the nut flush draw makes it more likely they have cards round the 67 straight range, so one has probably hit on this turn.
