2 pair vs likely flush

[MJL]

It happens often enough that you flop a good hand but the board looks scary like this.
How do you play? Like I did, agressive untill someone fights back?
I'm TAA, MP2 is vLPP and MP3 Is vvL(68%)AA. Both have went to showdown on almost anything. They like to catch flushes when you play big pairs.
