That's true, but of course test results are only valid until the next "risky" encounter.
If someone has shown a pattern of frequent high risk behavior, I think it's in any SPs best interest to take a pass, or at least insist on heightened restrictions for safety reasons.
I guess the problem is, the safer SPs {as distinct from low track types,
for example}, have virtually no clue who their customers have been
with or what their state of health is. And most guys are not going to
tell them if they were getting a BBBJ earlier that day around Hastings
and Main street, or the like.
OTOH any lady can see from my posts what i've been up to, if they
can believe and understand them, since a large percentage are BS,
BSing, and fooling around, with no real ill intentions. Last i heard,
though, Missy Mariposa is not suffering any life threatening effects
from performing a two hour BBBJ. In fact the size of her twins has
increased since our rendezvous. And, as all guys know, ladies who
give oral often every day are immunized from breast cancer. So,
you see, i was really doing her a favor.
