Am I playing scared again? flopped trips...line check

I am kinda new in this session so no good reads here. I have been real tight so far, like 16/14, and I think I haven't showed down anything yet. Villain seems Slag, pfring and cbetting kinda often (can't find stats), but I haven't seen him showdown anything.

Being new to 100nl, and not having a good read, I played this more timidly then usual...thinking on the flop, I call to try and get another bet from a worse hand (pocket pair/bluff/draw/trip worse kicker), and also to keep the pot small at first. But there's a draw out and I should protect and/or build a pot since I'm likely ahead. The turn I raised kinda weak planning to fold to a 3bet, or value bet/call a bet on a non-flush river if called.

What do you think?

Stack sizes:
UTG: $52.10
Hero: $110
Button: $85.55
SB: $108

Pre-flop: (5 players) Hero is CO with K J
UTG calls, Hero raises to $4, Button folds, SB calls, 2 folds.

Flop: 6 K K ($10, 2 players)
SB bets $5, Hero calls???.

Turn: T ($20, 2 players)
SB bets $10, Hero raises to $25????

Raise the flop, they'll never give you credit for a K. As played it looks very much like you have a king by waiting until the turn. As played I guess it's fine, but not optimal.

Thanks.I think I should've raised the flop too. I've seen people call me in the SB with K6o as much as KQ+ at this level so far. I think playing some more hands at 100nl will get me back into the right mindset (not too timid).
