I would definitely agree that bbbj is readily and openly available from any number of MPA's and SP's in the GTA. It's routinely offered, at least in my experience, and anecdotal evidence would suggest it's on the rise.
As for bbfs, I've had it offered a few times and have to admit gave in during the heat of the moment on one occasion some 7-8 years ago. Although I remained "clean" from the experience, it completely spooked me for months afterwards. I stayed away from the hobby for about a year, literally lost sleep worrying over it, got the full battery of tests numerous times and broke into a cold sweat anytime I felt any sort of twinge down below. Definitely not worth the short, albeit warm, wet and velvety, few minutes of pleasure it afforded.
I suspect more of us have given into this urge than will admit it....the heat of the moment and all....But what about the SP???? Why would they allow it? That really doesn't make any sense whatsoever to me.
I've also noticed from my experiences outside North America that bbbj is all but universally offered and bbfs is readily available and at least, if not more, common than finding a bbbj in the GTA.
As for the risks, well I'm no doctor, but it would seem to me that any "hobby" has risks and we're all exposed to varying degrees depending on the frequency and type of services we obtain.
Regardless, I think its safe to say that in all cases, the risks are significantly higher for the SP/MPA than for us. Obviously this is something each SP/MPA should seriously consider and understand given their chosen profession. And something each of us should respect once a particular SP/MPA states what/where their limits are.
