Party $50/100 - pocket 5s hit perfect

My image is bad as I've been running bad and having to fold to raises from continuation betting the turn. SB in this hand is solid and my view of him is as such. MP plus 1 is loose/bad.

MP+1 limps, 2 others limp I limp in LP, SB completes and BB checks. A23 flop with 2 spades and it's checked around to me. I bet. I'm not sure how I feel about this bet. Anybody hate/love it? If called I'll probably continue bet the turn unimproved. SB hesitates and calls, MP+1 calls.

Turn is the 4 of clubs, [img]/images/graemlins/grin.gif[/img] it's checked to me I bet, SB raises, MP+1 calls I 3 bet, SB caps and all call.

River is a 9. SB checks, MP+1 checks I bet SB raises, MP+1 folds and I call.

I have a couple questions. Who hates my flop bet? Who hates my river bet? I think the turn cap is standard to charge the flush draw. Results to follow.

Sorry if some of this is elementary but I was doing great when I first started in the $50/100 and now I'm getting shelled and am in that "I don't know if anything I do is right anymore" syndrome.
