In the house I currently live in, the hot water doesn’t last for long in the shower. I started PE one week ago, and do the 5 minute warm-up the second I get into the shower. After I finish the warmup I wash my body for a few minutes. In the few minutes where I am actually showering, the water is on the colder side. I make sure to shower as quickly as possible, and do my best to avoid the cold water hitting my penis. Is the few minutes in cold water negatively affecting my gains?
