Actually, I think you’re doing the analogy a disservice.
What you want to say is, tickling is how Martians ask for consent.
I.e., Martians ultimately want to get humans onto the mothership for experimentation, and humans actually enjoy being on the mothership (with some Martians, anyways), but in order to do so they have to communicate with the human—and the only way to do that is to tickle their ears with their tentacles (hey, it’s how Martians communicate.) And green Martians have stinging barbs on their tentacles.
So the first act a Martian has to perform is to get consent to tickle the human’s ears with its tentacles—AND THE ONLY WAY IT CAN DO THAT IS BY TICKLING THE HUMAN’S EARS WITH ITS TENTACLES.
