Long story short, I normally see GFE providers, unless the pics are hot enough, then I will occasionally make the exception.  My question is mainly for the providers.  I was recently with a provider who offered GFE, we got down to business and after going at it doggie I guess the moment got the better of me and when I came I ripped off the condom and jerked off on her ass.  She seemed to like it and backed up grinding my dick on her ass some more.  

Assuming she's got a bunch of reviews, read the Juicy Details and see if other guys report having done some version of COB. While you can never totally rely on the Juicy Details if there's a consistent mention of COB then it's probably OK.  Also, if in her profile it says she permits CIM, that's a good indicator as well.
Then again, when you get close to finishing you could also say, "Can I come on your ass?"  You could even ask, "Please?" LOL.

My limited experience is that as long as things are safe and below the neck - no biggie.  As an example- her tits...  that said, frank communication on this issue and others before getting down to it always seems welcome in my limited experience..

to always ask if it is ok first.You don't want to be disrespectful to the ladies and assume that it is ok.

prefer you to cum ON their ass rather than IN their ass, so if you're going to rip off the cover, keep the load OUTSIDE.   If you avoid hair and eyes when you shoot, all is well.  

Guys should ask before coming anywhere on a lady.  But The guys probably already know that they should simply ask about most things.  But providers shouldn't make the mistake of thinking guys are OK with everything because a lot of guys are very cautious.  I've heard from clients about some providers just doing BBFS (twice, with two different ladies I know) without asking if it's OK, just assuming the guys will want it if they're going to offer it.  And the men were not okay with that. I have seen a provider do a Stripper slide without asking if that's OK first. Grinding a cock on an ass is like doing a stripper slide and I think before doing any of these things we should ask each other if it's OK.

Also backs up the advice above to ask first.

Why not simply ask before hand? I can see this going very poorly. Not everyone wants your bodily fluids all over them.

Communication! Ask.  
Even if websites, reviews state certain things, I still always ask or discuss beforehand about Anything. No awkward, pissed, or getting your face smacked or worse. A smooth session is a better one.

Surprised by his orgasm. I was surprised too when it landed on my mouth. Shit happens. Ask her if that was ok, explain why and if necessary apologize and move on

While we're clearly sex workers, consent is always something that has to be maintained, so asking is always important, even if you know the answer is a yes. The worst that should ever happen is that your told no. Thank you for pointing out that asking is a good thing.

That a PSE provider wouldn't be ok with that. As a provider that inhabits an area somewhere in between GFE and PSE, this has never been an issue for me, short CIM, which is a no-go. From the the next down I'm totally game for COB. I'm kind of preferential to my tits or bits. I like seeing it, just not tasting it (some of y'all eat some trash food which has an impact... kick that cucumber and kiwi intake up👌🏼), and I like to play with it. While a guy is standing there after he's cum on my tots, I usually use his dick as a paintbrush and smear that baby batter around and let him admire his handy work for a little bit.

Haha I would have to agree with this!
