All that matters is statistics, not opinions or propaganda.
And the simple fact is that as a result of decreased condom use for vaginal and anal intercourse, STIs have been on the increase in recent years.
Global HIV, viral hepatitis epidemics and sexually transmitted infections (STIs) continue to pose significant public health challenges, causing 2.5 million deaths each year, according to a new WHO report - Implementing the global health sector strategies on HIV, viral hepatitis and sexually...

That decreased condom use for vaginal sex has creeped into sex work, unfortunately. Sex with a sex worker is not any different than sex with a “civilian” in spite of the media nonsense. The STI percentage for “upper-end“ sex workers has always been lower than the general population, and the STI percentage for street hookers has always been higher than the general population. The media and abolitionists focus on the street scene to justify their misleading claims. There are lies, damned lies, then there are statistics, as the famous saying goes.
No doubt as BBFS has increased in general society, the STI rates have gone up in general society, and as the percentage of sex workers who offer it has gone up, the percentage of those sex workers (and their customers) who get an STI will increase.
I just saw a new sex worker in a U.S. city a week or so ago (new to me, a rerun for her many regulars) and she has a lot of knowledge and interest in the industry. She was hardly inhibited since she was fetish friendly, loved anal play, and did BBBJ and CIM. She was concerned about the number of ladies offering BBFS and said it mostly started with Asian agencies. This seems true worldwide. There are a number of posts on the Punter Planet board about the predominant Asian incall place having ladies write notes during the session offering BBFS for an upsell.
I do think the trend of a few escorts who also do porn offering BBFS if a full test was taken within a few days prior contributes to the problem, also. The problem isn’t with the sex with those escorts, it is the fact that lower cost escorts see it and then offer BBFS without the tests.
Personally, I don’t get it. If a person can’t finish in a condom, just book an escort who allows a finish in her mouth and/or hand. It feels just as good.
But I also think the propaganda lovers who continue to be resistant to BBBJ even though the statistics and practical case studies don’t support the hypothesis that BBBJ, and even CIM, are significant STI transmission risks are part of the problem. They are the little boy that continued to cry wolf for so long, that everyone ignores him when the real wolf (STIs from BBFS) arrives.
I find it somewhat amusing that a profession that is viewed by enough of a segment of the population so immoral that it is in itself illegal, passes it's own moral indignation of the degree some SPs offer service.
