Im currently on my 8th day of nofap and cold showers have been a big help since day 1. all i did was turn the knob down to the bottom all this time. Accept today,I got used to the coldnest. On my shower there is a second knob with a cold option which I decided to do it and I tell you it was like liquid ice. I turned it back to normal and immidiently tell the temputer change. It felt warm not cold and had to change it back. But I dont want to damage my body with this ice liquid. So how cold would you say a cold shower be.
