My step-son has never been diagnosed with a disorder, but maybe someone here can help guide me. I believe he fits in somewhere on the Autism spectrum. Urination problems are very common for that group, but his behavior seems to be more associated with conduct disorder. His urine trouble used to be involuntary. Now intentional and repeated voluntary peeing on dirty laundry, carpet and mattress in his own bedroom is an ongoing battle. For a while he was peeing in bottles and hoarding them. He alternates between different 'tricks' for urinating in inappropriate places. This seems to mainly be a lack of consideration of others and the consequences of his decisions.
