Your post brought back a fond memory. I am a big fan of the Indigo Girls whose fans are largely female. At least their concerts are 90% female. When I go to the loo, the lines are tragically long at the womens and non-existent at the men's room. Inevitably some of the women come to the mens side and use the stalls. I dont object, of course , since all Gods creatures got to pee!
One time, though, I got a surprise as two very sexy 20 something women came in and pushed up to the urinals on either side of me. They quickly apologized, but they both pulled their jeans shorts down to their knees and PEED standing up at the urinal. They were amused at my laughter and the one on my left backed up so I could see her talent. She pulled her labia apart with two fingers and seemed to spray less than I did!
My wife is one of these talented females. She loves to pee outside and made sure our grand daughter knew how also. She has taught many a young female in distress how to pee in nature. As for the bathroom line factor, she has no issues going into the mens room if it to long of a line. Hell we went to a country singer concert and the mens room was packed but the womens line was so long. Next think i knew about 25 young women under the age of 20 came into the mens rooms and took over the stalls. A few guys turned while in process to see what was happening. Everyone had a laugh but we all got to pee. LOL
