Go to the hustler in vegas...the bathrooms are co-ed...blew my mind to stand there taking a leak and women doing their makeup in the mirror. I didn't think much of it at first, I was there to party, but then it hit me, wtf is this I thought...
Long as they keep it clean, I'm good. Sometimes, at concerts or out clubbing, the line for the girl's bathroom is ridiculous and the guys usually moves pretty quick, so I just use one of the stalls in the guy's - no one seems to mind.
Our school had bathrooms for one gender on one floor, and for the other gender on the other floor. Our floor was Men, and who would want to walk up the stairs all the time... we just all used Men, and for three years, nobody's ever complained.
It's been a long time since I've honestly confused a normal bathroom function with a sexual activity. ( Hey, trying to be serious here!) So, if it's a classy enough place to be and stay clean, then I can do my business with those of the other gender on the other side of a divider. I guess if it's not a bathroom function I'm there to accomplish, then the gender of those standing by is even less of a concern.
l'd prefer not to pee, poop, and pass gas in public restrooms where women are present. Blame it on my upbringing if you will. I really don't want to see and hear women peeing and pooping.
I had an after school/summer job in high school where one of my duties was cleaning the public restrooms ar a restaurant, bar, and hotel lobby. While men are bad to pee on the floor around urinals, the women's restrooms were always in equally but different filthy condition.
Seriously, do some women treat tossing tampons into trash receptacles like long range basketball shots? Not only lying around the floor but stuck, yes, stuck to the wall. And peeing all over the toilet seats. I actually vomited while trying to clean that restroom.
Keep public restrooms separate.
