I play bad, but was the river 'sexy'?

Final Pot: 11 BB

Button is a 24/15/2.0 type. SB is unknown. I was planning on 3betting preflop, until the SB called.

Flop I figured didn't help anybody, thought I'd take a shot.

Turn I feel strongly i'm in front. If he raised I was calling and folding a K,Q or heart river.

River it was possible he backdoored hearts, but I thought it more likely he called with 2 bigs. I thought i'd give him a chance to represent the Ace, figuring he'd call if it hit him and if it didn't I wouldn't have to show. I was folding to a 3bet.

Is this a little too loose, a little too laggy?
