Cumming in the morning ruins my desire to seek out something fun to do [with my dick] later in the day. Work from home has given me far more time with my cock than ever before - and I dig this, but..... yeah, when I unload before I log in for work, the rest of my day is all about work. And look, I'm way more productive working from home but I do miss that 'all day desire'.
The one exception I tend to make is on gym days. I do way better at the gym, want to stay there longer, work harder, and then let the jizz out after gym time.
