Cocks on socks blog — balls
The best time to check is either during or just after a warm shower or bath, standing up, as this is when your balls will be at their most accessible. It’s important to feel all around each of the balls because lumps can pop up in any part.
Everyone’s balls are different and although they should be roughly the same size and weight, it’s not uncommon for one to be larger than the other and hang lower. To gauge weight, cup your balls in your hand and move up and down.
