Come on guys don't kidd yourselves, BBFS has been going on since the beginning of mongering and it will not be the downfall of the hobby, and its not just the K-girls it's many of the girls in this hobby (i didnt say all), some of your favorites do it with selected clients, its the evolution of the monger/provider relationship that may happen, in the past it was taboo to talk about it and you would be ostracized for mentioning it.. so why does it concern you?
Simple if you hear someone BB's then avoid that person if you have concerns, but don't be surprise that a girl that says she never does it actually does. This hobby is illegal in most places so this is you the pot calling the kettle black..
We are adult enough to make our own decisions in this hobby, some guys like it up the rear, others like bbw's, others only like white, black, asian, or indian girls... that's the thing, how a person plays is not a norm, this hobby is not a norm the only thing we have is respect to our providers and fellow mongers our opinions are our own and should not be placed upon others because we ourselves do not play that way... that my friend is what society thinks about us we are not the norm but who cares... do it your way.
and i guess to answer your question.. i have done BB in the past, do i do it all the time? nope last time it happened was on a 12 hr date with a girl i had seen over 3 yrs before it happened, she never BB anyone (thats what she said) maybe true maybe not but it did happen.
