I'm another sitter in the dark. Or when I am very tired. Other than that I will stand. Of course, sometimes I will sit if I am reading a good book and know it will be a long piss (as I get older, these long pisses can become even longer what with the lessened power of the stream - Too Much Information
)
I remember in the early days, my Lady tried to convince me of the multiple benefits of sitting while peeing at all times, day and night. My thought was, as a man I will stand unless I lose the use of my legs. If I sprinkle when I tinkle I'm a sweetie and wipe the seat, see.
