Bet the River?

[sx3_turbo]

EDIT: I'm a MORON and choose poor examples.

Here's my real question. I have QQ and hit Qxx (two of the cards are suited) on the flop. I have 3+ people call down to the river when the river card puts three to a flush on the board. If I'm first to act, do I still bet into the pot? Would I fold for any reason? I would guess it's obvious someone has a flush if it came back to me capped. I'll try and pick better hands to post as examples next time. I hate myself.
