ELI5: The nerve cluster that is reachable via q-tip into the ear canal, it feels amazing. Why is it so pleasurable? Is there a purpose?

I was once told that there is a different reason why it feels so good. Earwax is a protective coating which prevents your ears from itching. When you clean your ears with a q-tip, they start to itch because there is no wax to protect them from it. Then you basically end up scratching your ears with the q-tip, and scratching something that feels itchy usually feels fucking amazing.
