50NL, baby flush on paired board

Dont have the HH because PT doesn't work with my site and I dont want to dig through logs and logs to find it.

I am BTN, full stack. 50NL FR, full table.

I hold 6h3h on the button. I limp in with 5 others, and there are 6 to the flop.

Flop: Ts Jh Qh. Pot: $3

UTG fullstack leads for 3. UTG+1 fullstack calls. Folds to me, I call.

Turn: Kh. Pot: $12

Checked down to me, I bet 7. UTG folds, UTG+1 calls.

River: Qs Pot: $26

UTG+1 leads for $10 and has $25 behind. No reads on either player. Do I just call here or do I get it all in and stack Ax? How often is this a boat/higher flush?

At first I thought I would push just because thats why you play 63s in the first place, but after thinking more about it I would just call. The only hands that call you if you shove will probably beat you so really why push it. Just call and win or lose anyone paying attention is going to think your a loose player playing atc so maybe they'll pay you off on a big hand later.
