I find this site so interesting!!
I do this in the morning, in the stall shower of the small bathroom my wife and I share. Sometimes I lube my right hand with the cream rinse, or shampoo, sometimes not. First I stand upright, and stroke until my penis is erect, this seems to go faster if my wife putting on her makeup at the sink, sometimes she will watch. Then I squat as I continue to stroke, this feels great with the hot water is falling on my head and running down my back. Often I push with my left fingers between anus and balls, there are other variations. Clean up is easy, a great way to begin the day.
