My wife recently peed out doors stood up like a man. This possible for most women , she had gone commando and had a long dress on. It was late early morning and were in the middle of nowhere. She lent back against the car , bunched her dress up around her waist. Feet well apart , knees slightly bent. Then pulled herself open and and up towards her belly button. To watch her pee just like a man almost straight forward was so erotic. The whole scen was so so horny. I was hard before she'd even started peeing.
Still not really sure why. I don't want be peed on but it was such a turn on.
