Flop of Fear?

Don't know about you, but the flop that stops me near dead in my tracks is the Axx flush flop. Especially when it hits me square in the nuts (pun intended). Either I have the Ace paired with no suit, or I filled the flush on the flop and have lots of enticing possibilities. It is the pair or two pair on the flop without any of the suit that gets me.

I have noticed lately that a lot of folks bluff at a flop like this. I do on occasion myself, but if I don't have at least one of that suit, I get real cautious. Position plays big with this flop.

What do you do?
