A K. Man, did I screw this up!

[kongo_totte]

Party NL$50 Full ring. $1 BB. Both me and Villain(UTG) have about $80. No reads, except, the table is fairly loose. Even looser than Party usually is. I'm dealt As Kc

Villain makes it $2 UTG.
2 call
I make it $7 from SB and all call (hmmm). 4 to the flop

Flop ($28): 3d Ks 6h

I bet $20
Villain re-raises $40
2 folds.
I trow up and call

Turn ($108)

I check
Villain puts me all in for $40 more. I fold and slap myself in the face.

How bad is my flop call?
