Party $25/6m: BB, unraised pot, catch tiny piece of flop

[otctrader]

Table is very aggro preflop, post-flop lots of checking around if unraised. Hardly an exciting hand but I post this since the situation comes up often. You catch a tiny piece of an unraised flop with draws galore out there (not yours); is it worth throwing anything out there on the flop? The turn?

Sometimes I'll bet the flop, but usually I check the flop and bet $1 on the turn. I'd also fold to almost any raise, so I don't know how wise my line is.
