Ditched an SB about six weeks back, as she cheated on me. We had an exclusivity deal which I did not adhere to. Sorry. But I found she was fucking others. I did not care about that, but her performance and sexual appetite was down substantially. I felt like I was married to her.  
Then I saw an inquiry about her on a different site and others talking about their recent experiences with her. So I knew why the performance was down. May be she was trying to make money for the upcoming holidays. All very fine, but I was not getting my money's worth so moved on.

I really don't want to know such things about the SB's I see.  

The very nature of a SD-SB arrangement precludes the concept of "cheating."  Unless you are paying ALL of her expenses, including having her live with you and be available to you 24x7x365, she can, and will be seeking time with other SD's or even just meeting civvie guys in bars and sport fucking.  It is the height of naiveté to think her promise of monogamy is sincere.  Just like you have no intention of being monogamous with her, as you said above.  
.
I have heard many (even most) of the SB's  I see tell me that they want one, special SD and after finding me they stopped looking.  With the exception of one, none of them has deactivated their SA profile and they log in regularly.  I would be foolish to think that the sugar I am providing them covers every possible funding need they have. To be clear, I expect my cat to stay in the house all the time, not my pussy. Even my current #1 SB who I just took to Australia for a month, has other SD's she sees.  I know this from 3 observations:  1. My alt SA profile received a message from her. 2. I saw her phone light up on an incoming call from a contact called "Rick-SD". 3. She borrowed my iPad for the trip and when she returned it she had forgotten to wipe her email and contact data off of it.  I wiped it all, but not before I spent an interesting afternoon shamelessly snooping through it.  
.
To be fair, I prefer not to know about these, but sometimes I am grateful for them. I told her what my sugar budget for her is and that I can't/wont exceed it.  So when she just HAS to get that new hand bag or maybe cover her power bill and I've already paid out my limit I don't have to deal with her whining. She knows (because I occasionally mention it) that either of us can end the arrangement at any time for any reason.  She also knows that splitting up would be much more of a problem for her than for me. If she pisses me off she risks losing my sugar. If I piss her off, I "risk" having to find new pussy to fuck (which I already have!).  
.
So, if she really wants more, she can go work for it - however she defines "work." As long as she is safe - and we still share test results regularly - I don't care and I don't have the right to care.  
.
Bottom line:  
1. SB's will come and go. It's the nature of the sugar bowl. That thing where you lock down a long term, monogamous relationship for year after miserable year is called "marriage."  I'll pass on that! :p  
2. Evaluate your SB based only on your time and activities with her, not by what (or who!) she may be doing when you are not together.  
3. Plan on every/all SB's to drift away over time. Keep at least one POT SB on deck and a few more in the dugout.

I think he said he didn't care if she cheated, just that because of it he felt her performance suffered.

I tell sugar babies that they can and should seek other sugar daddies as well as continue fucking others their own age.  I’ve had a few of them deactivate their SA profiles and stop seeing others for as long as I’m banging them regularly.  I don’t ask about their others, but they tell me this because I say it’s okay and I see that their profiles are inactive for months.  

I don't care about cheating. I do care about performance. That's what made me ditch her. Agree with the rest of your post

but the chicas themselves are every bit as health conscious as even the high end girls here in the states.

I am not a big fan - but I'm stoked you like it there grandad... Like you I go to CR quite often...

I simply commented that the girls are tested and as disease free as any of the girls working right here at home. The Del Rey itself is a shithole and I pretty much quit staying there years ago.

You think I'm saying my girls are celibate when I'm not there?!?

As for Guaro, my Guaro days are well behind me. Four of us drank about 20 bottles of that nasty shit on NYE in Bogota several years back, it gave me the worst hangover I can remember in decades.  

I moved and cant see them regularly so what the hell. They need money. He wants pussy. Win. Win. Lol

You Sir, are a true gentleman!

If you have a sloppy seconds in the LA/San Fernando Valley area, please have them shower off and send me their deets.  :P

I just realized from reading my regional board that the infamous GaG is in my town, go figure!  heh

I’m there, too....

Outside of the place in the 90s - I was rolled by (say maybe 10) kids... Oldest was maybe 16. I went down swinging but they sent me to the hospital with no money and no passport...

You guys can send any spares down here to the OC😉

There are more here than I know what to do with. I’m telling 10s I only have time to see them once a month. Sure, there are probably more in LA, but more of them also seem to have serious GPS and it’s hard to work around that when you have to travel to see each other.
