Cravings

First pregnancy.
I have never liked peanut butter but can not stop thinking about and wanting it (obviously a craving) however when I'm eating it just tastes ok, but not lovely or amazing just satisfying however as soon iv eaten it I just want it again like its the most amazing thing iv ever eaten. 
Anyone else had cravings like this? As a craving I just assumed I'd LOVED the taste of it x
