Why is my rectum always itchy

All of the above.

So you're just going to post this knowing full well some people have a prolapsed rectum, been in accidents, or have a deformed rectum and you're just gonna flaunt the fact that you have a fully formed rectum? Fucking christ! This is what's wrong with the modern world! So many of you assholes make yourselves feel superior and flaunt your privilege. As if people's lives aren't hard enough. People like you are cancer to this earth and that itself is offensive to cancer patients because cancer patients have more decency than you. Fuck you and your rectum you scumbag!!

Since you live in a climate with high humidity I'm guessing tapeworm.

I get itching periodically around my anus due to eczema. I also get hemorrhoids, partly due to excessive alcohol intake.

Because like half of the damned weirdys on iin, you never shower.

You probably have some angry hemorrhoids. Eat more fiber.

You're probably not washing your ass.

Itching is almost always caused by improper wiping. It may sound nasty, but looking at the toilet paper after you've wiped helps you know if your butt is really clean or not. If you wipe only once it most likely isn't. Take a douche before wiping whenever possible, it cleans faster and better. Not properly cleaning your poop can actually cause imfections.

Improper wiping. Push out with your butthole when wiping so it gets the inside area better. Itll make you have to wipe way more but its more hygienic and your arsehoe wont itch.
