Is it normal that i bite the hard skin off the tips of ny fingers?

don't worry, i do the same thing... i don't know why or how it started...its kinda embarrassing going for manicures, but im actually starting to stop....instead of biting my nail/finger, i either put on hand sanitizer cuz it makes ur finger taste gross, or i bite my lip...but not like legit bite...just like the thing that most people do in a tough situation

That's called dermatillomania Google it...that should help you

Not very hygenic.

Yer I have that habit. It sometimes makes my fingers bleed.

it's normal, in fact, i can even feel when you press "M" with that finger....

I bite/pick the skin off my thumbs. I used to do it to my pinky.

My mother wrongly accused me of being a masochist when I was about 5 or 6, because I did this. I found it soothing so, I liked it, but there was nothing sexual about it.

It's called Dermatillomania. I also have Trichomania. Apparently, the two are in the same class. I guess it's a form of self harm. I suggest you look both up. There are allot of people that have this, but they are too ashamed to admit it. I often find myself being jealous of others, because they don't have self-harm on their hands. I've learned to deal with it, but I hate when people ask to see my hands. My doctors have been fairly kind about it and they don't bring it up. There are some risk to it like infection,etc. Just look it up on wiki and should get better insight on this.

Good Luck!
