The "relevancy of unprotected sex to HIV infection" is captured right on point in this video in the starkest possible terms. To be brutally honest, some things about biology haven't changed since 1985.
One of them is the consequence of becoming infected with HIV for the great majority of people - eventual full-blown AIDS, and it is a bad one, worth taking precautions and changing behaviors to prevent.
Yes, the disease is now treatable (at least for those in developed Western countries) and that those who live with it can have healthy, full productive lives . . . but at the enormous personal cost of lifelong, unrelieved dependence on advanced, intrusive, constantly shifting and often toxic and unpredictable drug treatment and blood monitoring, a regimen that can come to define their lives. This is not just "taking a pill." No human worthy of the name I've met that is going through it would wish it on anyone. And yes, the brutal truth is that the choice HIV+ people face - lifelong treatment or certain illness and death - can an all come from ONE episode of unprotected sex, exactly as shown in the video.
The way to prevent HIV infection is also the same today as as it was in 1985 . . . personal choices to use condoms, to have safer sex, and to encourage other to make similar choices, each and every time they have sex.
Preventing and treating HIV is about biology, and protecting our bodies from harm, not about any emotional significance we attach to sex. The implication is that there is NO sex of any kind without some health risk, and their never has been, but to say so is not being sex-negative or anti-gay. That video might as well have been about a str8 or bi couple. HIV doesn't care about your orientation, of if you're out or not, if you don't like condoms, or "trust" your boyfriend, or about our community debates about being sex-positive or not.
And once and for all . . . avoiding HIV infection is NOT a call to avoid HIV+ men as pariahs, nor is portaying graphic symptoms of illness a slur against HIV+ men.
Being HIV- or HIV+ says nothing at all about the content of anyone's character . . . but there are other things that do. One test is what sense of responsibility you have towards others, and whether you don't mind causing needless suffering to get your kicks. By that token, guys who are HIV+ and don't INSIST on protecting EVERY sex partner from infection - the ones who go ahead and expose others because it's the other guy's "adult" choice - are probably getting all the scorn they deserve.
