I'm going to request that you to do a GOOGLE.COM search. Type in the words "p 0 r nO HIV". This is for adults only. Rough language.
You need to know what is happening in the p 0 r no industry. This is what can happen with just one guy who is irresponsible. And this blows your theory about everyone being TESTED.
Anyone who thinks about joining the p 0 r no industry for endless fun and glorious sex, or for money, ought to know they are playing with DEATH! At this point HIV means eventual death. There is NO KNOWN CURE. All we've been able to do so far is hold it off a bit...at a huge price.
