clench your ass and jump in the shower and continue clenching until you’re done
Lots of screaming.
Built up my tolerance over time. After working out, I’d start the water off cold and slowly make my way under it as I start to tolerate more and more. You’ll notice that over time, you’ll be able to get under the water sooner and sooner without having to incrementally increase the water temperature.
It feels good after doing very hot water first then cool down with cold water.
