Is it a fetish or a kink to enjoy ear biting/kissing/licking/sucking

It's not a fetish or kink. It's just something you like. Not kinky at all. Quite normal, in fact.

I think it could be considered your own personal kink. I love getting my neck bitten, a little choked, some ass slapping ;) , just some rough things. But I don't consider it a fetish cause that's not the only thing that can get me totally turned on. I also like going at a softer pace too, like soft and slow kisses. So no, I don't think your ear biting thing is a fetish. It's normal :)

Normal horny stuff...

It's neither, just good old sexual stimulation and fun.

It's a fetish, if it's either, but that's defining "fetish" pretty broadly. Ear nomming is super common.
