Is it normal to have an itchy butthole?

It's because you didn't clean your butthole i swear

Worms.

Try soap and water once in a while. Does your underwear have skid marks in them?

You should go to the doctor instead of asking question here

soap and water wash your dirty ass

U like the smell?

Do you have hemorrhoids?

You have worms, go to the pharmacy and buy de-worming syrup, drink it, shit the worms out and Voila, no more itchy anus!

You could have Yeast Infection
