I know ADULT men who will only poop at home unless there are really extraordinary circumstances. This used to drive me bonkers until I spoke iwth one adult openly. Boy were my eyes opened and I no longer make a big deal if we have to go home a bit early because this issue.
Have you ever been inside the boys bathrooms at your child's school? In a gas station? In a restroom? In a stadium? In any public place? They are VERY different from women's bathrooms for the most part. Many do not have stall doors. My husband was SHOCKED as a teen when cleaning the ladies restroom at the ball fields where he worked in the summer. He didn't know women's bathrooms had stall doors. He had only rarely seen them before. He attended at least 5 different schools as a kid and NONE had doors on the stalls - IF they had stalls and not urinals and a john in a big open room with a few 1-2 foot dividers between them (1-2 feet from wall to the end of the divider).
There is almost NEVER toilet paper in public men's rooms. Many places simply do not stock it - sometimes because it gets stolen, sometimes because the holders get broken and/or it gets tossed on the floor or into the toilet as soon as they stock it and sometimes guys have just peed on the roll so often that places stop putting it out. Then again, there are guys who wouldn't ever think about putting TP into men's rooms. I once worked in a convenience store and we got a magazine for convenience store owners. It actually had a poll about if you put TP into men's rooms or not back in the early 90s. At the time I thought it was a joke, but I was annoyed because every night I worked I had to put all new rolls of TP into the men's room when I cleaned it.
Men's bathrooms are DISGUSTING. Almost universally disgusting. Go into about 10 of them if you can. First thing you will notice is the horrendous odor that will assault you. They stink - even when cleaned more often than womens. Sure, some places have nicer ones - there ARE nice ones out there. They are a sign that someone puts a LOT of work into cleaning and frequent repainting. I know one business that paints the ladies' room every 1-2 years and the men's room every 6 months. The walls in the men's room have to be scrubbed down weekly - and this is a very nice, high end business.
This is one reason, in my opinion, that a LOT of guys have a really hard time with many bathroom things that we think are everyday things. I have been told that mens rooms don't have stall doors because guys tear them off, tear them up and pee all over them. I have no clue if this is true, but I know that there is NO WAY that I can use a public bathroom with-o a door between me and everyone else. If the bathroom is really gross i won't go.
We took a trip to the nearest Sam's on thurs and had to stop at 2 places to find a bathroom for me to use on the way home. The first place was remodelling the bathroom and had a portable toilet out front. I HATE those and this one had two guys on their lunch hour standing outside trying to rock it while a buddy used it. NO WAY was I using that one. The second had a great bathroom, but husband went into the men's and walked back out because it was gross. I could SMELL it - cleaner and pee - as I went into the ladies room. NOT really nice smelling, but there was no smell of pee in the air or anything else gross in the ladies room.
I DO keep a few ziploc bags in the car - each filled with 3 indiv wrapped sanitizing hand towelettes, a smaller ziploc with 3 baby wipes, and about 3 feet of toilet paper. I also have a spray bottle of alcohol in my purse. It came as a sprayer of hand sanitizer and is a little thicker than a nice pen and when it was used up I just filled it with alcohol to use on hands, toilets, tables, anything germy. My guys can grab a ziploc from the car and be able to use a public restroom fairly easily. Both the outer ziploc and the inner one with the baby wipes are in sandwich size ziplocs because these will fit easily into a pocket and hold all they need, plus they can put the trash into the ziploc when they are done instead of flushing.
Sometimes the problem isn't so much not being willing to do it as not being able to do it everywhere. I have seen the difference in men's rooms all across the country in all sorts of businesses - did a family poll and asked members who travel to let me know if there was a big difference in mens and womens restrooms. Part of my curiosity on this was because at the time I had a very young daughter and wondered if it would be hard for husband if he had to travel with her with-o me. It was -he did take a trip with just her one year and it was very difficult because she wasn't really old enough to navigate a ladies room by herself.
