@pylonguy71 With careful prior research re transport options and locations, you may be able to squeeze in a massage at Arena and then book a boy from Moonlight during your layover. Given your preference for the more muscular types, these may be the least-bad options. I dare not say these are good options, because I don't know what you're expecting. The Asian body is not naturally thick like a European body, so it's much harder for an Asian to get as much mass as a European. What you may notice from this board is that (exceptions permitting) the twink lovers generally prefer Thailand and the muscle worshippers have a bias towards Brazil.
@DenverDude is probably right about your luggage being tagged all the way to your final destination, so make sure you have what you need for the 16 hours in Bangkok in your carry-on.  
Although it may sound like a crazy idea to some others, I have done something similar before, during a 13- or 14-hour layover in Amsterdam, though it was a single cum, not twice. So it can be done. But then, I already knew the layout of the city from previous visits (making navigation much easier) whereas you're saying you've never been to Bangkok before.
Arena Massage largely closes by about 9pm. I once made the mistake of getting there around 8pm and there weren't many boys left. But if your flight lands at 3pm, you may be able to make it there by 6pm which I think is their peak hour.
This can be followed by a bit of dinner and then off to Moonlight for the show at 10:30pm. Get a boy by 11:30 or 12 midnight and use the short-time rooms at Suriwongse Hotel next door. Leave for the airport around 4am, perhaps? However, I don't think the short-time rooms are available for more than 1 or 2 hours, so it may be better to get a regular room in Suriwongse. It's going to be basic, but probably good enough for a few hours. Alternatively, the Raya Hotel almost across the street from Moonlight (it only has regular rooms, not short-time rooms).
To make this work, you will need to understand the locations well, the transport system and have enough cash. It's a little worrying that you're not asking these logistical questions.

One more thing, if you are checking your bags, even with a 16 hour connection, they may be tagged through to the final destination.  This was the case for me once on a 14 hour connection (that wasn't in BKK though).  You might check with Thai Airways to see what their policy is, you may not need that luggage storage.

I scored a very well priced Thai Airways business class ticket that has a 16 hour stopover (land 3pm and leave 7.20am) so I jumped on it as I’ve never been to Bangkok and have been very keen to sample the boy bars there. Plan is to clear immigration and store my luggage at the airport (I checked and there is a service doing this) then head into down, get some dinner then hit the clubs and hopefully off a guy or two!
read about Tawan’s unfortunate closing and that they MAY be reopened by my June 5 arrival. Given they’re the main source of my type (more muscular and very fitness model types, not into twinks) was wondering if anyone could provide names of other venues that would be good to check out on a Wednesday night? Also what time is best to go out there? And one last question, given my layover I won’t be booking a hotel or sleeping, so what are the options in terms of places to take guys for an off?
many thanks in advance for your collective wisdom!

Why don't you just book an inexpensive hotel?  The Quarter Silom (right by the Tawan Bar location) is only like $50 a night.  Then you would have a place to take your offs, not to mention be able to get cleaned up before you go back to the airport the next morning.

Thanks.
I’ve found that that they want you to have a good experience because that leads to repeat business. I trust my instincts and am always looking for the guys who smile and appear at ease. I keep in mind that they, too, want to come away feeling good about themselves.

Had a wonderful skilled massage and afters on Silom Soi 6 last night. 
The guys are mostly outside shops and very approachsble. You’ll find that a surprising number are conversational in English.
Don’t hesitate to chat them up. 

That's because there is a market for it !
I had a guy the other night tell me he had a farang in Jomtien who pays 2k to watch him jerk off & cum 

Such negotiations happen quite often in the massage shops of that area (I think you meant Silom 6). Management seems to want to maintain an image that these are proper massage places, even when the boys don't really know how to do one. So the boys are left to look after their own interests when the shop does not set a minimum tip as done in some other massage shops, e.g. in the Saphan Khwai area.

Halfway through a massage at Relax in Silom 8, the masseur stops everything (I hate when they do that) and starts negotiating (which I really hate) and says it will be 500 baht extra tip for him to come. I couldn't believe this as I could care less if he comes - that is not my goal here - and asked him to repeat his proposal. He repeated it. I laughed and told him if he comes he owes ME the tip!
He didn't come. I did. Don't you love a story with a happy ending?
 

Last night arround 8.30 at least 8  guys from there on the corner. Good Samaritan looking like KFC man and dressed like myself passed by, grabbed one boy , went with him to 7 /11 a bought 500 baht worth of beer for boys to warm themselves up in these chilly +30 degrees evening.

Yesterday's observations. 
Screwboys now is GoodBoys but according to mamasan that is only change made.
Hot Male beer bar street level at 8 .30 more staff than customers.
Went to Jupiter with another member at 10.15. Singer was singing trying to.m outscream himself. What waste of talent. After 30.mi uses I was ready to leave but mercifully walkabout started. Lots of new faces, more than half never seen before which I take as good sign. Tipped most deserving for looks in my eyes hoping for some vague smile or at least an eye contact but ot to avail.
So one sarcastic may say "all normal ". Had he smiled off would be in the books as I freshly exchanged money. As consolation boy I offed in July last year while sitting with another client , recognized me, smiled and came to shake hands . Made my visit there and restored himself on the "Good guys from Jupiter " list.
We were only two farang in audience. At one point I counted 8 guys sitting with customers but only one of them with man.
I was hoping to spot three guys but none of them in the roster yesterday. Add to this 4 guys I was hoping to see in Pattaya in previous 2 days,  who were also gone at least temporarily and warning comes to mind not to count on seeing guy we are dreaming about before our trip.
Show bit more progressive than used to be with  ot one but two rigid members presented unobstructively.
Former New Twilight and then Queens Club is now @smiles , lesbian bar for tomboys according to handsome guy who emerged from the door.
Banana Club packed for the show at midnight but only 3 farangs detected including undersigned humble nobody.

If they need to change name hopefully it will be to Sun / tawan in Thai /.
Thank.you for an uplifting report. Not all hope lost it seems.

Confirming your findings from my walk at arround 8 pm. Two guys were already on duty on the corner. It seems , from my talk to them that they also have some hope for reopening but probability that it will be under new name was mentioned by one of them.

No dispute that there were more choices  in the past. But did most of us really used it? Perhaps expats or people on 3 months vacations.
I like it better now because it's now and presents options I can use currently.
Boys I was drooling about 10 years ago now are  often balding , developing respectable waist size and often trying to forget about their past job.
For me no memory substitutes for moment I'm entering bar  and spa now, curious as ever what I will find on other side of door . If I dream I rather visualize  my first walk next trip through soi 4  toward Jupiter on my way greeted by owner of G'Bangkok or barkers at Banana then recall some exciting first walk through soi Twilight bak in 2015 as much as I miss it. But it's gone   .
On merit of Sunee it's easy for me as I never really considered the place substitute to my more favorable digs - Boyztown. I liked Good Boys though but still can't say I missed it since it's not there anymore.

I believe shop with rent/sale sign is former site of much missed Coffee Grinder.

that's another issue we face, flying several hours at substantial cost hoping to reclaim it by meeting guy or guys we dreamed about since last trip only to learn they left business and returned home, got married, got drafted to the army , found a job with more permanent foundations or simply disappeared into thin air or even worse, got permanent sponsor who  claimed ownership of his time .
Even worse and I know about at least one case - boy went out of shape and only remotely resembles one we dreamed about with running away screaming most suitable option.
