So even if a provider does BBBJ I noticed many won't be at it for too long. Any solid providers here in Los Angeles are good at BBBJTC? Any possible recommendations? Thanks.

I know one girl who has been doing it for eight years.  No need to take it off the menu.  

Do an advanced search for Cum In Mouth.  Those are the ones that do it the longest with each customer.  

The advanced search feature is there for guys like YOU that want a particular service.  The program with sort it out for you.

That is a great idea, for some reason I have assumed CIM to be somewhat separate from BBBJ. Thank you for the suggestion!
