im a person for years now who has after wiping inspected it smelled it and i have done the same after i pee. i think its something people should do once in a while so you know what is a normal smell and look and what is not. i dont know if thats true but this is my answer to life long questions.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
