Based on some of the responses I've read on different threads over the past weeks, I've come to understand that there are certain clients who don't understand that ways in which they show up might have an impact on the overall mutual enjoyment (or lack thereof) during a date. Maybe it's "the customer is always right" mentality taken to an extreme especially because of the overlap with skewed views about sex workers.  

 
From what I can tell, some are convinced that just having cash in hand and showing up is all that's required. However there is a range of things a client can do to contribute effort to a date being fun, or even phenomenal. Many of those things are touched on in the etiquette sections of many companions' websites. There are even "good client guide" blog posts that have gained traction. I think Tryst has something similar as well on their site with solid advice.

 
Even in platonic / friendship contexts, I've been blown away when thinking about the distinction between how men are socialized when it comes to feminized tasks and labor such as house chores and cleaning. I've seen 30 or 40 something men left to their own devices who keep their home space in the wildest condition. And I get that sometimes life can get overwhelming. Still, when you're hosting someone, you either get it together or coordinate another option. Even with civilian dating, many people would understand the example of wanting to shower in a bathroom that's clean. But I think some men think a mystery maternal figure appears out of nowhere to do the cleaning they are supposed to do *or* that their partners and playmates are supposed to wallow in a weird situation with them while somehow still being sexy and turned on.

 
Similarly, I think some men are not mindful or aware of how to prepare for the sex that they say they want. Manicured hands and trimmed nails for digital penetration is a must as Bia said. Anal prep and internal cleansing comes to mind as well. If you really want to experience rimming which feels amazing, there are things you have to do to facilitate that fantasy being a reality. Hopefully people engage earnestly with what's touched on the original post.

While I get the general idea, this reads like a rather privileged post. A manicure, pedicure and manscaping, and hire a cleaning service?!?!? None of this is necessary. I regularly clip and file my own nails, both fingers and toes. I shave my junk area every week, and always freshly the morning before a booking. I am more than capable of keeping my house clean, though I never would have a provider over to my personal residence. If I am booking an outcall, it's because I am staying at a hotel. And, I keep my room well kept. I don't think anyone capable of addressing the important part of this needs to be told how to do it. It should not matter whether someone is hired or if it's self managed. In the end, as long as the person and the place is well kept, how it got there is not of any significance.

This shouldn’t be aimed at clients only as it’s really a bigger issue with people in the lifestyle in general. Anyone who has been around p4p long enough as a client has probably seen it all i.e. poor hygiene, a dirty incall, bad breath, or obvious, oft putting signs that someone was in the room with the girl just prior to us entering.
.
The problem is that the people who need these reminders the most, be they male or female are often the same people who don’t realize they even have a problem to begin with. Think about it QB...if someone has to be told to shower, take care of their nails, wear clean clothes, or make sure their breath is fresh, how much is a reminder in a forum like this really going to change them?  
.
The reality is that some people simply were never taught basic self care or even proper manners. Others may be dealing with things like depression, addiction, mental health issues, or may be on the spectrum and struggle with certain daily routines that most of us take fpr granted.  
.
Then add in todays crazy lifestyle, where many adults spend hours every day gaming all alone, are glued to their phones, and are constantly distracted by life coming at them, with all its stresses and unknowns and it’s not that surprising at all that some people lose site of the basics. I am not excusing it, of course, as I pride myeslf in being squeaky clean but it seems to me there are more troubled souls now than ever.

This reminds me of an experience i have at least once a week when I go out to dinner. I see a lady dressed in heels and a flattering dress, and her date is wearing his best sweatshirt, dirty jeans and flip-flops. For Fuck's sake--why do women put up with this?! Make an effort man!

As for P4P, what you advise is what I've done for as long as I've played. The problem--as others have pointed out--is that your message will not penetrate to where the unkempt, disheveled, funky and unclean make congress. Your message will be met by a solid wall of dirt and denial.
