Hmm, patchy at best. I was involved in a massive research project for sociology in college which opened my eyes. Apparently the rate of STD transmission is higher than those working in the illegal sex trade because condoms are not used in the majority of scenes. STD testing is only mandatory for some of the big production companies, a lot of amateur or small companies are a lot looser with their testing.

I could go on about more stuff but I'm foggy with the flu.
