Our female took almost 3 years to be fully potty trained. Now with my 2 year old male we are still struggling with it. They have access outside all the time through the dog door but I genuinely believe he just prefers to poop/pee inside. Especially when it rains, and we live in WA so that's a lot. I'm at my wits end but I love him so much so I keep trying to figure out how to fix it. He will pee on the couch or bed if he gets the chance but I limit access to those places and have hard surfaces in my lower floor for easy clean up. I'm starting to wonder if a litter box would be a better option since he is so stubborn about going out.
