My Son Urinates Sitting And Leaks On Floor

If so how do you handle this.
My son urinates sitting and leaks on floor. He would crash at night and not wake up enough so while he did not wet the bed his carpet got it the floor in the bathroom the ac furnace vent the tub the sink. I bought some clorox wipes for him to wipe afterwards but its just not getting into his thick skull. For weeks now i have smelling an awful smell in the game room and his bed room. 2 days later i found a wet spot on his floor.
I m frustrated that my 13 year old is peeing all over the back of the toilet and the front of the toilet. My 10yr old son has been urinating in his closet and floor. The bathroom he shares with his sister is always smelling of old urine. This has been going on since he was about 10.
Now he used to wipe down the ring of the toilet with tissue when he used to stand true but that is merely spreading the pee pee all over so women now have to sit on dried urine. He admitted to it when i was putting the dog outside. I had to train my ex husband to sit while peeing. I thought it was our dog until i caught him urinating in his closet and again one moring when i got him up for school.
He again admitted he did it. First for the leaks it can simply come down to potty posture. As little girls begin to transition away from kid sized potty seats and sit on the big potty seat it alters their seated posture. Biomom put him on concerta kept upping the dose.
He was fully awake and when i asked him why he just said because i had to go. I have a 4 and a half year old son who is getting very good at using the toilet but i have noticed when he sits down on the toilet to pee the stream goes through the toilet bowl and the seat and it leaks down onto the floor. Boys peeing sitting down. Webmd looks at encopresis a condition in which children defecate outside the toilet along with other elimination disorders like bed wetting.
My son jett was diagnosis d as adhd in 2nd grade. He first urinated on the couch and blamed it on the dog. Since then i have found our recliner wet and he has admitted to doing that as.
