Is it normal to have a nail fetish (long, unpolished)?

Firstly, I'm unsure whether to put this under the "sex" section, or "urges and desires" section. Sorry if it's in the wrong section.

I'm a straight male and I have a nail fetish. I'm attracted to nails that are long (anything above the fingertip) (nothing more than ~2cm above the fingertip either), and they must be unpainted; completely bare (and natural). Anything else is a turn off to me. I'm currently not sure whether the nails just "get me going" or I'm outright attracted to them, but it's definitely a fetish, and also probably partialism.

I've looked on various websites and I've found only the one single mention of this fetish, so already it seems *fairly* uncommon.

So my question is this: Is this fetish a common one? If not, does it even exist for anyone else at all? Thank you (read on for further info)

(More detailed information) (Explicit): If I'm having sex, I can still reach orgasm and not be sexually frustrated from someone with bitten nails (my only other experience so far), but when I do it with someone who fits my fetish, it's a lot better and I come away a lot more relieved.

What spurred me to write this post is that when my girlfriend (who fits my fetish absolutely perfectly) cut her nails, it affected me inside and I don't think someone without a fetish can understand that. We haven't done anything yet, but already I'm sexually frustrated and I know the next time won't be as great. My girlfriend does know about my fetish. Thanks again.
