Should I eat my own skin?
What makes you want to eat your own skin?
I don't know why.
Eating your own skin is unappealing. If it's a compulsion, you might want to get professional help so that you don't damage your skin and cause permanent scarring.
It's cool and makes me happy. It's not harming anyone so what is wrong with it?
It's not harming others, but it is harming yourself. You shouldn't be drawn to damaging yourself like that. Treat your body with the utmost care so that you can live a healthy and active life.
