Is it normal that i like the taste of myself?

I was watching a tv show when suddenly i noticed that I was eating of myslf, I couldn help it. I tasted too good. I am affraid to take chunks or bite untill it bleeds, because I do not want to get addicted to hurting myself. I think I would like it if I was bleeding too, cause blood really tastes good.

Anyways, I do not really taste as good in the shower or shortly after a shower.
