pavlovian theorizing

Whenever I come home to my house I always have to go to the bathroom. I think it's a learned action, like Pavlov and his dog: hear the bell, salivate; come home, go to the bathroom. It doesn't matter if I've just gone 10 minutes before, if I leave the house, say to take out the trash and recycling, as soon as I get back into the house and enter my room, my bladder is calling for attention again. Maybe it is a medical condition I should get looked at. Maybe I just need to retrain my brain to think about something else when I get home. Like dancing.
