I can't imagine someone touching their genitals and not washing their hands afterward. The last person who went out that restroom door may have had poop on their hands. And you think I'm going to touch it???????
See, that's what I get for joking. Yes, I do wash my hands and always have. I nearly washed my skin off during the first part of the pandemic before it was known how Covid spread. Now, I'm back to my norm of washing before and after everything. Still tired of cooking though.
Someone once did a study of how many people wash their hands after using the toilet in a public restroom. I think they put a hidden camera in some of them. A lot of people didn't wash up afterward.
I always put out a fresh towel for guests and after they leave it goes straight in the laundry basket. My sister puts out a towel for guests and keeps another one in a drawer just for herself. Just the way we were raised I guess.
Data from an environmental microbiologist indicated that the dirtiest part of any public restroom--either (or any) sex is the handle on the men's urinal when there is one. Men have dirty hands and parts and the handles are never cleaned by staff, as are toilet seats and toilet handles. I am told by some that women's public restrooms are the smelliest due to "squatters" who have poor aim. Don't know personally. Throughout my working career I probably washed my hands 20 or more times every day, so I still wash frequently and whenever I go to public places such as stores--grocery stores with carts especially--I wash my hands when I get home. Contrary to public perception, hand washing well is better than sanitizer but sanitizer with conditioners is easier on the skin. That is largely why towards the end of the "pandemic", the use of hand sanitizer was seldom mentioned, although it was strongly encouraged at the beginning. Alcohol "kills" the virus in vitro, but the evidence in situ is that PROPER washing is better as the virus is removed from the skin and is less likely to "hide" in debris on the skin. Wipes also remove contaminants from hard surfaces, but the spray-and-go products do not except bleach, which is assumed to denature anything organic.
Now that @Don Alaska mentions the handles on public bathrooms, I remember that before the self-flushing units came along, I would flush the commode using my foot and the urinal using my elbow. I have noticed that some public bathrooms have installed foot-grab devices on the bottom of the doors so you can open them with your feet. And some stores (like Walmart and Lowes) have large bathrooms configured so there is no entrance door...you walk in and go around a corner.
Poop and pee on one's hands are NOT going to do damage to them. Just don't put your hands in your mouth.... I can just hear members gasping for breath after reading some of this Medicine info. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3032615/
Nevertheless, I will choose to wash my hands on such occasions. In fact, I go a step further and do my best to prevent these substances from getting on my hands, to begin with. One never knows for sure, though, so I wash. I will strive for poop-free and pee-free hands. There are things that I can control, and there are those that I can't control, so I will control those that I can, for as long as I can.
Years ago--before you couldn't tell the truth of such things--there were stories about a rash of e. coli illnesses following an undocumented housekeeper/cook around who lacked basic hygiene skills. When someone in the household took ill, she'd disappear and get hired somewhere else.
I'd say most who are so germ phobia, wear the great and wonderful CDC masks now over 3 yrs later. I wore 1 two times, both for doc appts....
I grew up on a farm yet, even as a child, I washed my hands of such stuff. Of course, since I spent a lot of time in the woods, washing wasn't always a practical measure, so I was careful about what I got on them.
As far as dirty genitals, I can think of other things that are really dirty and they are not genitals.
