I don't know what gender you are, but as a woman, I've used the men's room. They don't always have urinals. A lot of the newer ones don't. So the 5yr old in your example is unlikely to see anything. Although I think she's pretty unlikely to see anything anyway even with urinals?Yeah sorry never been in non gender bathroom.
And thank you I do teach my girls all the right things about others. Like I said I think more of the extreme cases where people take advantage of it.
Maybe I'm intruding on those delicate flowers that are manly men, but honestly, sometimes I just can't wait in the hour long line for the woman's restroom.
Honestly my biggest objection to gender neutral bathroom use is that some men seem genuinely confused about what target they should be aiming for. But then again some women also object to touching their bottom to the seat which is a whole different topic...
