Enjoying pornography is not inherently damaging to males or females. However I would use some cautions. There are individuals who most likely shouldn't view porn, like those with poor body image or those who have been sexually victimized. Depending on your choice in viewing, you can establish impractical expectations about sex or what people like or how you'll be expected to "carry out." And watching with somebody requires true consent.
When none of these warnings are up, porn can definitely have advantages. Therapists in some cases recommend it to help people become comfortable with a specific dream they or their partner might have. Porn can reboot a couple's sex life. It can provide you ideas, or help you contact what turns you on.
Pornography can reboot a couple's sex life. It can give you ideas, or assist you connect with what turns you on. Pornography can provide you there at best, or disgust you at worst. It all depends upon what you choose to see. With the schedule of pornography online, it's possible to sample sufficient porn rapidly that you don't need to find yourself enjoying wall-to-wall hard-core sex if it's plot driven erotica that attract you. You're only 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 initially. There are some who select to carry out since they like sex a lot and they consider it an excellent way to earn money. Then there are those who are drawn to porn as a way of acting out subconscious mental issues-- 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 psychological health will face some disadvantages from this work. Our culture consumes pornography at record numbers, but the females who perform are still evaluated roughly.
I'm uncertain the male entertainers get out entirely unscathed either. While they might not be judged as roughly as the females, ultimately 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 so consumed with regret and embarassment about sex, neither viewing nor carrying out in these films would bring the weight it does. But then, possibly we would not be so interested in them, either. If the fruit were not prohibited, would anyone care to read more take a bite?
