Back 5 or 6 years ago or so, there was a website where you could learn in detail how to pee standing up without any kind of device. My friend said her grandmother was the long skirt-wearing kind and she regularly peed standing up. It entails lifting the labia and pulling outward, and the exact technique depends on your own personal anatomy.

I looked for the website again, because it was quite humorous in addition to being helpful, but most of the hits were ads for devices. Wish I had the link.
