Echoing the sentiments of others: he’s a sweet, prime beef specimen. Easygoing yet engaged, we talked for a bit to get comfortable with each other, but once the session started our mouths rarely parted. I hadn’t been active in quite some time, plus it was my first time with a provider, and he made me feel at ease.  Gorgeous human inside and out.

The primary photo does come back to someone who lives in Vancouver, so that's promising.

so how much washing is required? fully soaped up ALL areas of body, including under arms, under balls, inside ass crack, around or even a little inside your hole, fully cover your cock and pull back foreskin if you have one, rinse all water off. Repeat if you can. then fully dry off. ideally brush teeth or at least gargle some mouthwash to freshen up if you are wanting kissing. You should wash yourself with vigor and be overly thorough. Treat it as if someone is about to inspect every inch of your body - which is generally what happens in a massage!  Not just a quick rinse of water over your back or some water splashed on your face. 
Just because the client showered, does not mean he has done so properly.  Not everyone has the awareness of hygiene, and it is really awkward and difficult to tell someone without offending. 
True Story - I offered a gentleman to have a shower when he arrived dripping with sweat and B.O and he said "i showered this morning." I said, "well I had one 10 minutes before you arrived, why don't you have another one now and freshen up - don't worry about the time it takes to be all clean, the session will not start until you are out of the bathroom."   A normal person would read between the lines and go and throughly clean themselves, but this guy was in and out in probably under a minute.  During the session he wanted me to suck him off and when I went down there I had to cut the session and say 'look we need a break, I need you to go back and really take your time cleaning up and washing everything down there, ok?'  he replied "but why?"  like I said earlier - OBLIVIOUS. I don't know if he wasn't wiping his ass properly or not, but the smell of shit, ball sweat and pre-cum is not a pleasant aroma for the best of us. The second time he went in the shower for maybe 2 minutes. Clearly not clean.  I said, 'no no, let me come in with you' and had to wash him down myself.  

This is very accurate. Many people contact via rentmen asking for massage only, sometimes they may only want a sensual massage, or they are scared about writing down what they REALLY want, which is completely understandable (although frustrating at times) A lot of clients are nervous full stop.
Then there is a particular type of client that deliberately asks for massage only prices, but then try to receive full service upon meeting.  (I always make it clear of the price structure before hand to avoid this)
I fear the OP was offended when full service was not on the menu for the massage rate. Often rentmen are happy to upscale the session to full service rate when the client is comfortable (dick is rock hard) and asks for the next level. But by asking for massage only - it does also leave room for the provider to say "no this is massage only." And in cases where hygiene is an issue, well often the clients that have these issues are oblivious to it. 
The OP has left 6 contributions to the forums so far, 3 of which have ranged between completely negative to somewhat negative- and all mention MASSAGE ("great massage but not consistent" "i was 15 min late so we went straight to bed no massage and no offer to extend time" "airbnb was small") To me these comments indicate a client who is overly critical and extremely fussy,  Like someone who posts bad yelp reviews when a restaurant makes them wait 5min for a table or doesn't refill the water quick enough. 
The only way we will know the truth is if the provider or client chooses to post a screenshot of MASSAGE ONLY discussion which i encourage either to do - [whilst redacting identifying numbers/screen names of course and staying within forum rules] 

Thanks for reaffirming a very important point - your humanity.  Anyone can have a bad experience, but short of having a provider become violent or steal from you, it's not cool to trash someone with smears or insults. One of the things I (and many others) carry into any meeting with a provider is respect for the person who is offering himself quite literally for my enjoyment. 
I must say your education background is very impressive AND cool. 👍🏻

Yep, anyone with reasonable critical thinking skills will give more weight to the positive review from the member with a history of helpful posts than to the review from someone who joins to post one or two negative comments.  Wishing you the best!

I saw him a couple times about 30 years ago.  I thought he was the hottest provider around.  But the second time I saw him he gave me the clap and I never went back.

You don't men Daddys Reviews do you?  This is its successor.  If you click the Reviews tab at the top of this page you'll find the archive of that site.  If that's not what you're thinking of, I don't know.  I can't think of another one.

Well, before it was Daddy's it was Hooboy's site.  I don't remember the URL, but there's information here about the history:

I could never imagine negotiating price with a provider. That’s embarrassing. If the price isn’t to your liking move on. 

There is an active discussion on that very topic.

I have no personal information to share, but he's been previously discussed here:

He looks HAF and we need to quit this nonsense about a person's age. Beauty and talent is not the province of the very young!

It's now under the same name as his deli ad.

@PetetKsfo did a great job of explaining this. There is a option to set "Availability" and "Not Available" is a setting that the guy can toggle. The default is "Not Set." Here's what it looks like:

If the guy chooses "Available" or "Not Available" he then needs to specify a timeframe, anywhere from one hour to one week:

So as Pete mentions, setting "Not Available" would indicate the guy is not available right this moment, but is otherwise available at other times. It's a more short-term option, compared to freezing or hiding the listing which would indicate a longer-term absence or limitation.

I can set my status to "available"  "not-available" or "not set".
"Not set" is the default setting if  I am offline.
Once I log on, the setting changes to green and shows as "available"
I can also manually set myself as "available" so even if I am not right at the computer but cooking or doing laundry or something, I can keep the "available" light on for up to 6 hours.
If I know that I have a client booked in the afternoon, or if I am not available at all for a day because I have some other plans, I can change the setting to show as "not available"  - either for a number of hours, for a day, or a week - in order to not waste your time if you are looking for something right now.
So I would say that if you see a "not available" - it means the person is not available right now, or probably not for the next few hours, but may be available later or the next day.

Most search engines require at least three characters for searching to limit massive numbers of irrelevant results.  A quick test indicates that is true of CoM's search.

Same ole story. If you think he's a beauty, he hits all your buttons, he performs well and you're willing to pay his price then you hire him. If you refuse to pay more than $X under any circumstances then you keep looking. We sometimes get stuck on the notion that everyone should charge the same rate regardless of desirability and performance. There are all sorts of price points in this enterprise. There are all sorts of customers. BMW and AUDI cost more than Chevys. Yet nobody says they are all cars, or a car is just a car. 

I don't have any specific desire to be with a straight man just because he's straight, but I also don't care if a provider self identifies as straight.  I have hired providers who have identified as straight, bisexual, and gay.  What I care about is that I find them attractive, and they agree to what I am looking for when we discuss meeting.  I almost always check here (and previously on Daddy's old site) to get reliable information on others' experiences before I contact them.  I have had some great experiences with guys who identified as straight, and some not so great ones with guys who identified as gay.  I think you just have to do your due diligence and hope for the best.  And if they deliver on their promises, tip them well.
