Is it normal to have skidmarks on my knickers?

Wipe.

It's one of those "never ending wipe" poops? I had that problem a while back. I increased my water and fiber intake and the problem was eventually solved. Though that might not work for everyone.

Really gets the clagnuts off.

Try scrubbing your ass with your partner's toothbrush. It works for me.

Sounds really shitty!

Sure that's what your jocks are for, isn't it? Better on the jocks than your white bathrobe!

No skidmarks are for shit stains like you.

No! Wipe your ass!

No. In the morning wash really deep.
