You have to figure if they do CBJs, they already have it figured out. Non lubed condoms, flavored condoms, non latex condoms, or these are gals who really don't care about the condom taste.
Truth is most of the ladies who can't stand the taste of condoms do BBBJ, and most of the guys on TER prefer BBBJ, or only see ladies who do BBBJ, but TEHO.I hear quite often that the providers don't like the tastes of most lubricated condoms. What do the ladies do to prevent this problem? Do you use non-lubricated condoms for oral and then use lubricated condoms for vaginal sex? Or do you use non-lubricated condoms and ad flavored lubricants for oral sex?

Way back in the day, I did do only CBJ for awhile. I'd get the non-lubricated condoms for this, but they still taste like latex, of course. Occasionally, I bought the flavored/scented kind but those had a chalky taste and a weird aftertaste too.
Plus, the little tip thingy made me gag.
Some flavored lubricants can cause..... um.... feminine issues. So that's something you might want to be careful about using only for oral. 
Here's what I would suggest, so that you don't have to use separate condoms which would then necessitate "changing" in between oral and vaginal penetration.... which can definitely interrupt the natural flow and momentum.
Take an unlubricated, unflavored, unscented, basic condom. Put a little plain liquid lube on the INSIDE, then slip that bad-boy on. Now it's plain on the outside so you don't have the commercial lubricant taste, but slick & comfy on the inside.
Now your playmate for the day can suck away. If and when you decide to go for the gold, lube up on the outside and have at it!
Repeat as needed. :-P

What makes this a regional question? This is a perfect newbie general question?
Hope you had a great birthday because it seems like you are not recovered yet.
if he's that interested in that concept, he might want more input from providers in his area, than around the country.

some providers I've been with have mentioned that Trojan brand condoms have a very distinct (not the best) flavor while giving a BJ. Actually they gave said they don't like Trojan brand too much for sex, too. Some have used flavored conforms or flavored lube.
I don't think it's the lube that is the issue.
