25NL, Multi (and I mean Multi) Way pot

Table had been going batshit insane for the last 5 minutes, so figured I'd jump in. And I got all I could have hoped for. So why does it not feel right?

Ignoring my occasionally wrong gut, what do you guys do?

In a multiway pot (probably any pot), i like to keep the pot from ballooning too much unless i have a monster. For me, a straight on a paired board with more than 3 opp is not a monster board. I imagine you are afraid of a boat, with the raise on turn. But, if the table has been seeing a ridiculously high % of flops, the kicker on a 2 isn't necessarily an A. Still, i think even with the unfortunate possibility that a FD sees the river for cheap and hits you still just call turn. And then call river, unless a diamond/ A/ 5/ 2 hits. 75% of the time none of these cards should hit river, and i have to imagine you are good at least 75% of the time on the river if none of these cards hit. No software to run any calculations, though i imagine once i do get it i will sound a little more confident about those %'s. Did you c/f/r turn, c/f/r river?
