Quicky - good flop aggression or lucky play?

[IUPlaya]

I'm wondering what you think of my preflop aggression. Is it good to follow up preflop raise w/ aggression on flop with so many callers (one or two callers, I'm fairly confident in my play and would have probably bet pot). I had no real reads on any of the players. Also I meant to raise to 8 not 7.

Party Poker No-Limit Hold'em, $ Hero (6 max, 6 handed) converter

SB ($122.17)
Hero ($59.9)
UTG ($38)
MP ($111.55)
CO ($111.78)
Button ($37.85)

Preflop: Hero is BB with K, K. SB posts a blind of $0.5.
UTG calls $1, MP raises to $3, 2 folds, SB (poster) calls $2.50, Hero raises to $7, UTG calls $7, MP calls $5, SB calls $5.

Flop: ($32) A, J, 6 (4 players)
SB checks, Hero bets $24, UTG folds, MP folds, SB folds.

Final Pot: $56

The A is a scare card for you but also for everyone else.

Bet this flop ~90% of the time IMO.

Definitely re-raise more preflop with so many people in there. I bet half pot here. If someone has an ace, they aren't folding it to a pot bet either and if they don't, you want them to call...
