Enjoying porn is not inherently harmful to males or ladies. But I would provide some caveats. There are individuals who probably should not see porn, like those with bad body image or those who have been sexually taken advantage of. Depending upon your choice in watching, you can develop unrealistic expectations about sex or what people like or how you'll be expected to "carry out." And viewing with somebody needs true approval.
When none of these red flags are up, porn can definitely have advantages. Counselors in some cases suggest it to assist people become comfy with a specific fantasy they or their partner might have. Porn can reboot a couple's sex life. It can offer you concepts, or help you get in touch with what turns you on.
Pornography can reboot a couple's sex life. It can give you concepts, or help you connect with what turns you on. Porn can deliver you there at best, or disgust you at worst. It all depends on what you select to watch. With the schedule of porn online, it's possible to sample adequate porn rapidly that you don't need to find yourself viewing wall-to-wall hard-core sex if it's plot driven erotica that appeals to you. You're only a victim of bad pornography 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 women initially. There are some who select to perform since they like sex a lot and they consider it a great method to earn a living. Then there are those who are drawn to porn as a method of acting out subconscious mental problems-- searching for daddy's love or punishment for being a bad girl. For lots of, it's most likely a little of each. Even women with the very best mental health will face some downsides from this work. Our culture consumes pornography at record numbers, however the women who carry out are still evaluated harshly.
I'm not exactly sure the male entertainers get out completely untouched either. While they might not be judged as roughly as the females, ultimately they're viewed as freaks who make their living with their anatomy. John Holmes's fate is the supreme cautionary tale.
Maybe if we weren't still so taken in with guilt and shame about sex, neither watching nor carrying out in these movies would carry sex the weight it does. But then, maybe we would not be so interested in them, either. If the fruit were not forbidden, would anybody care to take a bite?
