Its unnatural and against the biology of the human body to put things into the place God created waste/dung/poop/feces to come out of . As a nurse, I know what I'm talking about. The desire for things against nature is not Gods plan. Whether you believe the Bible or not it is a sickness and perversion of the natural ways in biological creation. It will always eventually produce sickness, disease and destruction of the body. Whether it is now or in the future. It's not the way you were created. It's a lie and a great deception. The enemy of your soul comes to kill, steal and destroy. Killing pride you life by seeking truth in humility is thd first step to freedom.
