KKxx one pair calldown

[crashwhips]

Once again I think I might have spewed. Should I be leading turn here and if so I have to pitch it if he raises right? I didn't lead because I was wary of 67 and didn't want to be raised off what was possibly the best hand and/or the best draw. I decided to call on the turn because my hand could be good against a TJ straight draw/flush draw and if not I have the flush outs. On the river I thought missed draws were a big part of his range so I decided to call down. Was this horribly played?
