Nina Hartley - who is both a porn star and a registered nurse explains exactly why condoms in porn are a very bad idea.

"Why wouldn’t mandatory condoms make it even safer?

It’s a logical question but the answer is counterintuitive. Porn sex is a performance. It’s not like the sex most people have at home. Depressingly, Masters and Johnson found in their groundbreaking studies a few decades ago that the average American couple typically completes an act of sexual intercourse in about eleven minutes from foreplay to orgasm. That’s a sad thing and the subject for a post all its own, but it tells you nothing about what sex on a porn set is like.

Typically, because we shoot multiple angles on multiple positions, in addition to shooting stills, wrangling lights and cameras and other gear and dealing with technical problems of all sorts. It takes about two hours to shoot a good hardcore scene. Condoms were never intended for that kind of industrial use. Hard-ons come and go. Condoms roll down, come off, dry out, split and otherwise fail on sets about 30% of the time. I know this because I work mainly for Adam&Eve, one of the companies most supportive of performer choice when it comes to condom use, and Ernest and I have shot miles of condom footage. We’re left with little confidence regarding the efficacy of condoms for this application.

And speaking personally, I can tell you that they have, for many female performers, a serious drawback. I’ve taken a lot of crap for saying this in other places, but facts just refuse to conform to PC ideas of how things should work. Condoms, no matter how lubricated and how designed, create more internal friction on a woman’s intimate anatomy than human skin, with which it’s evolved to tolerate contact. All-condom players, and I’ve known many of them tend to turn up at clinics with raw internal tissues and multiple surface infections. This we call “condom rash” and it’s more than an annoyance. Intact tissues are the first line of defense against infection. If your insides are compromised by friction burns and low-grade bugs of whatever sort, you’re that much more vulnerable to whatever might be turned loose should a condom fail.

Those who have never worked as performers love to dismiss this as bullshit urban legend. Those who do that have zero experience with the realities of shooting a hardcore scene. Condoms make everything take longer. They make everything less comfortable for male and female players. They can’t be trusted to operate as intended. They create conditions conducive to contagion."
