Dirty bottom again 2-4 hours after bowel movement?

Hello.

So it's a bit of an uncomfortable topic, hence the anonymous one.

At least I never had that when I was younger.

So have a normal bowel movement. Wipe thoroughly, including putting some into your anus if possible.

After about 2-3 hours, it starts to itch slightly. I wipe up, and there's more AA residue on the toilet paper.

No, I'm not an old woman.

Is this normal or am I doing something wrong?
