Basically my idea is to sit in my bathtub in a short washtub with hot water (because it takes quite a lot of time to fill bathtub to the level of my navel), water heats up my entire groin area, then I stand up and do stretches/jelqs. Could it harm the balls in some way? I know you should care for the balls not to be cold, but how about too hot?
Thanks.
Thanks.
