I wouldn’t say I have a fetish for it. It is just something I have an interest in. However, I had done over a liter in one of my measuring jugs. I think it got up to 1000ml the first time I measured.
Second time, not in the same day. I poured out the contents twice into the toilet as it reached 1000ml and peed to like 500ml.
The toilet was so full after that, I immediately flushed it. twice.
