I have my own fingernails also, I had them when I was in school 30 years ago, before all the fake ones were so popular.
I went to Walmart and found Leather Ring Thimbles by EZ Quilting, they come three in a package, They go around your finger tip instead of going on top of yiur finger, So You can have really long nails, because your nail is poking out the top. It works Great for us with real nails. :D or fakes
