Live 1-2 NL, misplayed my hand. help?

So I had been playing for about 2 hours at his point. I was up to 200 with the average stack at the table being 400. It's a pretty loose game and everyone knows me as a tight/aggressive player. I had never played with these two guys involved in this hand before.

In 2nd pos. I have A [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/spade.gif[/img] I make the table's standard raise of 13. 3rd and 4th pos call me, everyone else folds.

Flop: 3 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/spade.gif[/img]
It gets checked around

Turn: 6 [img]/images/graemlins/spade.gif[/img]
I bet 10, fold, call

River: 9 [img]/images/graemlins/heart.gif[/img]
I check, he checks

Showdown: He had 10 [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/spade.gif[/img]

Ok so I know my river play was garbage, should I bet the flop here? I know this depends a lot on my reads but give me some advice.Thanks
