Depends these days. When I can fit it in etc. I prefer to shower before going out, so if I know I am heading out after lunch, I will wait till then to shower. Will often just do a quick sink wash with a face washer if I feel the need for a second wash or don't have time for a full shower of a morning (tank water here, so need to be careful with what we use)

When working I had to have to shower of a morning, I just need it, I can get quite sweaty overnight and being sweaty I need to put on fresh deodorant onto clean skin, or I will stink before lunch.

DH is a shower at night person and when we got together he insisted that I did as well. Funnily enough I started to get many bouts of thrush.
