That's because the spicy is felt thru thermoreceptors that "feel" if there is any heat, it happened that capsaicin can bond with this receptor, making you feel the spicyness; That receptor is found in both your mouth and your butt, since we don't really digest capsaicin since it's not useful for us, it get in to the shit

Edit: just realized that i wrote this in a science meme sub

Why is there a capsaicin receptor in the butt?

[-] DonPiano@feddit.org 25 points 2 months ago

It's a pain perceiver where capsaicin activates it.

Our senses run on chemicals, and that means sometimes chemicals activate these senses. Capsaicin is similar to a different chemical that our bodies use as signal, and binds to the receptor instead.

You could imagine it like a vending machine that's supposed to dispense soda if you put Euro coins in, but it'll equally dispense soda if you put other flat pieces of metal in it.

Superb explanation!
