Anastasia Steele: What if I told you that I feel the same way about being punished as you do about me touching you? Would you still want to punish me then?

Christian Grey: No. But that doesn’t mean I wouldn’t need to.

Anastasia Steele: Why?

Christian Grey: Ana, stop.

Anastasia Steele: Why do you need to?

Christian Grey: Because it’s the way I am! Because I am fifty shades of f*cked up.

From Fifty Shades of Grey (2015)
