Is it normal to enjoy knifing and stabbing fruit?

Ok when i was 15 i used to get a bunch of fruit like a apple or a handfull of grapes. Once i got the desired amount i start stabbing them with knives and cuttlery.

Thinking that i am actually killing the fruit and using differen't techniques on slicing them.

After this i clean up and i feel horny. I go masterbate afterwards.
