Caucasian skin can sometimes be difficult, it seems despite how white we see ourselves the reds become evident once we're photographed...I live in Asia and have an Asian wife, any time I attempt to shoot a portrait of both of us, these huge variations in skin tone become evident...I have spent countless hours attempting to balance the colours, I have various PP packages, neither provide a satisfactory outcome...I learnt after a while that sometimes B&W is the best course of action...
(As a side-note from experience in Asia, the whiter you can make the females here the happier they are)
So now with many if not all I shoot with the intention of converting to monochrome..
I think with your subject (no offence) he's a heavier set older gentleman, so despite your light/camera settings he is naturally going to be Red/a little shiny....as others have said you could use some make-up/powder (I could take a guess that this may not go to well with this gentleman).
This is where you as a photographer have to consider ways to show your client in the best way, a good B&W is timeless...
Not that it will solve all your problems, because you still have to find the best way to process the B&W image.
With some of the examples I personally don't think that over processing (blurring) male skin is the best option.
With females it is a little more acceptable (look at many of the movies of the past, soft shot for female, then hard shot for males)...all personal preference...
