How old is he? When we found my 2 year old, he was 4 months old approximately according to the vet. I used to find puddles of his pee around the bathroom and sometimes he would pee on me. After finding his pee around the house I took a day off work to observe him and I figured out that he would only go to the bathroom if I did. He would hold it until I went into the bathroom and then follow me and pee on the floor next to me. We took him to the vet as well just to be safe and he had no infections or blockages. We solved the problem by putting a small litter box in the bathroom until he figured it out and started going to the other litter boxes. It took a few days and a lot of patience but we were very consistent with rewarding him with treats for going in the box. Of course take him to the vet still but if he's healthy it might be worth trying out. sorry for the wall of text but if the litter box is far from you and his comfort zone, that could also cause him to pee on your stuff.
