Reported Speech - sentence with two verbs

Question

"Did it hurt when you touched the wire?", the doctor asked.

Let's say that we want to put the above sentence in reported speech.

Would it be

The doctor asked if it had hurt when I touched the wire.

or

The doctor asked if it had hurt when I had touched the wire.

I always find such sentences quite confusing.

Answer 1

While both sentences are grammatically correct, the first sounds much more natural.

If you wanted to use the wording of the second sentence, you could instead use: "The doctor asked if it hurt when I had touched the wire."
