Am I losing value here?

[Silly String]

When he called my flop raise, I had to put him on a better hand, yes? I thought AT. I probably should have re-raised the flop, but I didn't think everyone was coming along. This table hadn't been that loose.
Did I lose value not betting the river? Didn't think he would have Q, but worried about a set. Set bets river here right, or does he give me rope to bluff with?

Reraise preflop, bet river. Flop and turn seem fine.

[Renton]

don't ever let people see the flop for 2bb when you have AK in position.

[STIdrivr]

Ill bet the turn sometimes in position to get a free showdown possibly if I wanted

Reraise preflop, and bet the river. Yeah ..
