Many men don't know about this.
This is it
It's a bidet for men's urinals.
The nozzles are slightly different depending on the toilet.
The nozzle in the picture is easy to see, but some aren't.
(They press it against the toilet) It wasn't for peeing, but for 🌶️ washing.ㅋㅋㅋ Sometimes they wash their hands too.😹
It may be unfamiliar to Koreans, but this is a bidet, not toilet water...
It's part of the Islamic ritual washing (wudu) before prayer, so it should be seen as a culture.
