Of course it is necessary, here the question is not only in hygiene, but also in the banal habit of keeping your hands clean. Moreover, in toilets, where the door does not open in both directions with a kick of the foot, it is worth waiting for someone else to open the door and follow him. Well, ideally, you should always keep an antiseptic with you
Of course it does! I can give you two examples from life.
One of my colleagues at work had such a psychological disorder as the hero DiCaprio in the movie Aviator, but in a milder form (he always washed his hands, etc.). He tried to go out into the corridor as little as possible during rush hour, so as not to meet with his male colleagues and shake hands with them, so he had dinner later than everyone else. And once he blabbed that most of the men don't wash their hands after using the toilet! Girls, imagine, men touch their penis, and then shake your hand! Beeee.
The second case is my young man (originally from an eastern country, where urine is a substance that disrupts the state of ablution). Coming out of the toilet in public places, he also reported with horror in front of his eyes that the men in the toilet, having done their job, go straight to the exit.
It somehow passed on to me. Now, as soon as I see a man's hand outstretched when meeting, first of all I remember these stories.
So if from a sanitary and hygienic point of view you do not get infected and die, then at least wash your hands with a girl / wife after the toilet.
It makes sense to wash your hands BEFORE going to the toilet to urinate. Because a bunch of pathogens and just dirt gathers on your hands.
And then it makes sense to wash because, on the door handles, on the button of the flush tank and on the toilet seat, which may need to be lifted, there is also a bunch of BMOs. which should not be carried around the body and apartment.
There are two meanings. Cultural: In the toilet, you touched your genitals and may have been in contact with urine. It will be unpleasant for others to think that you could not wash your hands after this, especially if they witnessed that you have been to the toilet, but not in the bathroom (the combined bathroom, of course, becomes a life hack for the lazy person here). If you are alone, hand washing serves at least to develop a habit. Hygienic: in the toilet, for example, you came into contact with the toilet flush button. People who were not so scrupulous in the field of sexual hygiene could touch her. If you have been to a public toilet, washing your hands is all the more necessary: bacteria are in good order there.
