Well, this is an old topic. But I have to say, urine/pee is sterile and nothing gross about it. Nature intended even our feces/poo to be incorporated into the ground as a fertilizer. But I digress...
I have always enjoyed peeing outdoors. It gives such a sense of freedom. These days I travel a lot, and mostly on country roads where there are no facilities. I sit at the edge of my car's door opening, and pee to my heart's content. The tp goes in the car's trash bag. It is unhealthy to stress your bladder and kidneys by holding it in, till the next filthy gas station comes along.
On my property I just squat where I am. There are no neighbors in sight.
I am against being lady-like. Women have agreed to be these symbols of delicate, weak, needy existence, so that men can be the strong, rough guys. Oops, I digress again!
