Is piss fetishism common or looked down on?

When I was thirteen, I was watching an innocent kid's show. Two of the main characters made a bet and the loser had to stick a hose in their pants. There was several times in my early childhood that I noticed an apparent excitement to urination. I began to investigate this feeling at age thirteen and discovered it is legitimate feeling and I can gain sexual gratification from it. Even discussing it with friends I become sexual excited. But it disgusts me cause it seems abnormal to be sexually happy about something so disgusting. I am just curious how many people experience this kind of pleasure. For me a lot of it is the naughtiness. Like peeing in pants or underwear or on carpet/couches. Like peeing where you shouldn't be including public. I just don't like that even I feel disgusted by it while being turned on.
