Is it normal to do this in the kitchen?

Is it normal that i move my bowels in my kitchen sink? I know that sounds a little strange but when i do it, i have fun. Its different. I mean, I have a commode, but the sink is just different and fun for me. Plus, it takes over half a roll if tissue to clean myself if i use the commode, but in the sink i can use the spray hose and i know im clean that way. My friends dont come to see me anymore. They say im not who they thought i was. My parents have been puahing me to get help ever since i crapped in their sink. I guess i just dont see anything wrong with it.
