Nicko (ringneck) always LOVED kisses, he could sit on my arm for hours, squeaking for more kisses and nose cuddles - but never in his 20+ years did he like human hands (I was told - I only got to know him for 5 years before he passed, but he indeed did not let any fingers come near him during that time). He'd let me give him treats from my fingers, sure, but that was it. If a finger without a treat approached him, he'd bolt.
A fear/dislike of fingers seems pretty common especially in smaller birds - I know ringnecks especially are quite prone to not liking fingers at all.
I didn't mind though, I rarely even noticed that I couldn't use my fingers/hands to handle him - pretty much only when he wanted cuddles and I had to scritch him with my chin, nose and arm instead...
