Bf won’t clean up his pee on the floor

My boyfriend and I are 20 & 21, we have been together for 3 years and we live together. He is horrible at peeing IN the toilet. He pees everywhere, including the floor, down the front of the toilet, all over the side etc. We each do chores (I do all dishes, he does all laundry) but I do the majority of the deep cleaning like vacuuming, mopping and cleaning the bathroom. With that being said, I do not want to clean up his piss! Is it unreasonable of me to expect him to wipe down the floor and toilet with a clorox wipe every time he pees? I told him if he can’t do that then he needs to sit down, but now he’s pissed off.
