What feels good to a snake?

[NargleBeliever]

Hi everyone,

I'm curious about whether or not there are ways to "pet" your snake or otherwise interact with it in a way that feels good to the snake. With a dog, you would scratch behind its ears, rub its belly, etc. Are there particular spots or movements that would give your snake a similarly enjoyable experience?

This is all with the assumption that the snake knows you and is comfortable being handled by you, of course.

Thanks!
