When a client contacts someone I have introduced him to via a doubles it is not a problem.....I would strongly encourage him to seek out different ladies....the problem is....

....when the lady contacts a client I introduced her to via a doubles appt.....and the contact is made to the guy in a tone that pretty much says: Hey let's hook up without A`, we would have a much better time.

My client found it very distasteful. I found it very classless.....I obviously do not mind sharing....I love doing doubles, but I mean really? are times that hard?

To date I have never and will never say anything to the other lady, I wrote it off as a lesson learned, and I will never under any circumstances work with her again.

I would not see a lady I didn't have contact information on even for doubles.

I trust providers to screen for me like they trust me to screen for them, I would take it in consideration but I would still need to do my own screening. I would never have this issue. It shouldn't offend anyone if you want to do your own checking on those you're going to fuck. It is your safety too.

Now if I got really stupid and didn't screen, I don't see why it should be an issue as this is no strings attached sex after all. If I was a provider, which I am not, I would want my clients to see others as it would mean less attachment issues for me.

P.S. If any ladies want to pay me for sex, I would gladly give you contact information on any lady doubles partner we may have. Sorry I don't play with other male in the room. I am funny that way.

If anything, the second lady was more famous/infamous than my friend who arranged everything.  I later over the next two years saw the second lady over a dozen times separately.  I didn't need to ask my ATF for contact info...and my ATF didn't mind, either.  

Just go for it, dude.  Unless the 2nd lady is UTR, you shouldn't need to ask your primary...
