I would have folded 5th if there had been any significant action earlier.

You should be using the opposite logic with a drawing hand--there's less reason to continue here when the pot is laying you 2.15:1 on your 5th street call when you're 17.6% to make the hand on the next card. You're drawing to 6 outs in 34 unseen cards here with a very small pot... I'd let this one go.

edit: Oh... I'm not suggesting you should continue with 4-flushes against paired door cards even when the pot is a little bigger. But if you have a drawing hand heads up, you need a big enough size pot and good chances to win in order to continue.
