One distinction the reassurance should not swallow. Never having licked you is personality. A rabbit that used to lick and has stopped, alongside being less active, eating less or hiding more, is a different question entirely.
Rabbits are good at hiding discomfort and a sudden behaviour change is often the first thing an owner notices. Yours has been consistent for two years, so this is who she is. If it ever changes abruptly, that is worth a vet rather than a thread.
