Those events can actually be traumatic tho. Like I've explained before how I've had clients who didn't wash their ass when I worked at MP's and when I was massaging their back I could smell shit. I've found shit in showers at a massage parlor I worked at, after a client came by. I had a client who was morbidly obese who had a bunch of paper towels between folds of his skins because he was sweating and it was hot outside and removed them when he was in bed with me. That stuff kinda stays burned in your mind for a while. It's also that when we complain about clients here, everyone feels targeted..
But yeah most clients I have know how to shower and brush their mouth properly at this point lol I make sure to let them know they have to be clean, and I am also very clean. I am really lucky and privileged at this point because I am able to get clients who are respectful and take care of themselves before coming to see me. At some point as a provider you can demand that kind of respect from your clients and avoid bad behavior. That is also why I am so outspoken online, even if I know it rubs people the wrong way (and I understand why).. It's a strategy because if I'm very honest there are less chances of me attracting clients who are disrespectful, most of the time.
I also think that I think men who really enjoy seeing escorts and truly appreciate us know what to do to have an enjoyable session with us, they know that they have to show up clean and that they have to be polite.

They know the etiquette and they understand consent
