No.

I wouldn't include castration, but, do share a thing/fetish for long, digging nails with my hot older sister. She got my face by accident one time years ago, apologized, then I told her I liked it, and wanted her to do my back and arms. Started out moderate, just enough digging of her amazing, sexy nails into me, but soon became "draw blood" all the time.

I fixed her computer for her when she was in her old apartment, and was paid by an intense, on the floor, dig her nails into my back, arms, chest, and legs impaling by her. My body had streak marks all over it, and she took great pleasure in doing so, making her mark on me. Went on for a good hour or so. We've done it several times since and even have tells or signals for when she wants to.

castrate?!?!?!

It's a fetish. I wouldn't say it's abnormal just not common. Try listening to a band called Angelspit. Their music has been dubbed "erotic gore." You're normal, hopefully you'll find a girl with the same fetish as you.

"and having her long, sharp nails..." what? poke you in the eye? finger you rectum?

okay this one is a little odd, only because of the castrate part. to be attracted to pain is just a fetish and i have a fetish of my own so to have a fetish is completely normal, but to the sexually attracted to castration is going a little far.

That's not normal. Nuff said.
