Watching porn is not naturally damaging to males or females. However I would provide some caveats. There are individuals who probably should not view porn, like those with bad body image or those who have been sexually taken advantage of. Depending on your choice in watching, you can develop impractical expectations about sex or what people like or how you'll be anticipated to "perform." And watching with somebody requires real permission.
When none of these warnings are up, pornography can definitely have benefits. Counselors in some cases suggest it to assist people end up being comfortable with a specific fantasy they or their partner might have. Pornography can reboot a couple's sex life. It can give you concepts, or help you contact what turns you on.
Pornography can reboot a couple's sex life. It can offer you ideas, or assist you get in touch with what turns you on. Pornography can deliver you there at best, or disgust you at worst. All of it depends on what you pick to enjoy. With the availability of pornography online, it's possible to sample enough pornography quickly that you do not have to find yourself enjoying wall-to-wall hard-core sex if it's plot driven erotica that appeals to you. You're just a victim of bad porn if you let yourself be.
And a word about sex or pornography addiction. I do not believe in it. Unlike a chemical substance, like opiates, you can't end up being "addicted" to sex or porn; you can end up being a compulsive viewer. In this case, it's not the pornography that's the problem; it's the compulsive character. If it weren't porn being used to act out one's compulsive nature, it might be food or some other habits.
As for whether it's hazardous or beneficial to the performers, let's take ladies first. There are some who select to carry out since they like sex a lot and they consider it a great way to earn a living. Then there are those who are drawn to porn as a way of acting out subconscious mental problems-- trying to find daddy's love or punishment for being a bad lady. For many, it's most likely a little of each. Even women with the very best mental health will deal with some downsides from this work. Our culture consumes pornography at record numbers, but the females who perform are still evaluated harshly.
I'm unsure the male performers get out entirely unharmed either. While they might not be judged as roughly as the women, eventually they're considered as freaks who make their living with their anatomy. John Holmes's fate is the ultimate cautionary tale.
Maybe if we weren't still small tits porn so consumed with regret and shame about sex, neither enjoying nor carrying out in these films would bring the weight it does. But then, possibly we wouldn't be so interested in them, either. If the fruit were not prohibited, would anyone care to take a bite?
