Seeing porn is not naturally hazardous to men or females. But I would offer some cautions. There are people who probably should not view pornography, like those with bad body image or those who have been sexually taken advantage of. Depending upon your choice in watching, you can establish unrealistic expectations about sex or what individuals like or how you'll be expected to "perform." And enjoying with someone needs real consent.
When none of these warnings are up, pornography can certainly have advantages. Counselors often recommend it to help individuals become comfy with a specific fantasy they or their partner might have. Pornography can reboot a couple's sex life. It can offer you concepts, or help you connect with what turns you on.
Pornography can reboot a couple's sex life. It can offer you concepts, or help you connect with what turns you on. Porn can provide you there at best, or disgust you at worst. Everything depends on what you pick to view. With the schedule of porn online, it's possible to sample enough pornography quickly that you do not have to find yourself seeing wall-to-wall hard-core sex if it's plot driven erotica that attract you. You're only a victim of bad pornography if you let yourself be.
And a word about sex or porn dependency. I don't believe in it. Unlike a chemical compound, like opiates, you can't become "addicted" to sex or pornography; 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 damaging or beneficial to the performers, let's take females initially. There are some who choose to carry out because they like sex a lot and they consider it a terrific way to earn money. 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 penalty for being a bad girl. For numerous, it's probably a little of each. Even ladies with the best psychological health will face some drawbacks from this work. Our culture consumes pornography at record numbers, but the ladies who perform are still evaluated harshly.
I'm unsure the male performers go out completely untouched either. While they may not be evaluated as harshly 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 guilt and shame about sex, neither watching nor carrying out in these movies would bring the weight it does. But then, possibly we wouldn't be so interested porn in them, either. If the fruit were not prohibited, would anybody care to take a bite?
