ELI5: Why I often begin to suddenly lose control of my bowels as soon as I'm in sight range of a toilet

I'd like to know if there's an explanation for this phenomenon. It's happened to me my whole life, and it's something that really doesn't make a lot of sense to me. I'm able to keep control during a car ride, a long walk, or through a meeting, but as soon as I step through the door to the bathroom I'm suddenly getting the squirts and about to shit myself.

it is called a "conditioned response"

This has happened because for a very long time, you have walked into the bathroom, seen the toilet, and sat down and pooped.  Since your body likes to poop, when it sees the toilet now, it gets all excited and gets ready to poop before you have even sat down on the toilet.
