I've been calling down too much

I think you are probably looking at K4s or a slowplayed 66. I can't see AA or JJ. "Almost" everyone raises either of those pre-flop. I think A4s or A6s would have prompted a raise on the flop. Personally, unless you know this guy is tricky I think you are beat. But with 11BBs in the pot now and a few more to come (most likely) I think you have to call and hold your nose. Just expect to lose to trips 44s or 66s most of the time.
