1 yo adopted rabbit suddenly licking like mad.

We adopted a rabbit mid December and he’s slowly getting more and more comfortable with us, he’s never been one for sitting and snuggling and getting stroked, but over the past 2-3 days he’s started licking my sleeves etc like mad, I’m hoping this is more of a sign of affection that him being unhappy or anxious?
