This is sad news, but I'm sorry it's unlikely that Mason Wyler contracted HIV while filming one of his scenes bareback. Models who perform bareback, as well as all models I believe, are thoroughly tested on a very regular basis for obvious reasons.
If you say oral isn't safe either, what are you suggesting? People wear a rubber while getting a blowjob too? Even if you don't shoot your load directly into your partner's mouth, there is still plenty of cum that is released prior to ejaculation just due to pre-cumming. But then what if the rubber is defective and has a hole in it, and you have a cut in your mouth? You could still contract it even if your partner pulls out and cums by jacking off instead of cumming into his rubber.
I think the odds of contracting HIV by having sex with someone who has been recently tested and comes up negative are less than getting hit by a car while walking across the street, or dying in an airplane crash.
The only way to guarantee you're not going to contract HIV from sex is to abstain altogether. Period! Wearing a rubber doesn't guarantee you anything, although it does reduce your chances. It's much safer to limit your partners to those you trust, and who have been recently tested.
While the article doesn't specify how Mason Wyler contracted HIV, my guess is that he was with numerous sexual partners outside the controlled environment of the porn set on a very regular basis. I just hope his current employer had him tested frequently enough that he received the diagnosis prior to performing in a single scene while infected.
Personally, I don't think this story is about the dangers of bareback sex in porn as much as it is about what can happen if you have sex swith a lot of sexual partners you don't know, trust, and verify they are clean.
It's also a tragic story about Mason Wyler the person, and how his life has now been changed forever. I feel for him, and pray that he will get through this.
