Does anyone know the law as to what STI's mean a WL has to stop work?

Its highly highly likely that anyone who is promiscuous enough(having sex paid or unpaid makes no difference) will still catch diseases like herpes, warts etc even with the use of condoms. If your unlucky to kiss someone with Hep too that will transmit as well. Specially if you have been swapping tonsils with a DFK.

I am sure it doesn't stop any punters.

its why I can only really do a ML punt these days without any conscious or fear of repurcussions
