Seeing porn is not naturally hazardous to men or females. But I would offer some cautions. There are people who probably should not view 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 individuals like or how you'll be expected to "carry out." And enjoying with someone needs real consent.
When none of these warnings are up, pornography can certainly have advantages. Counselors often suggest it to help individuals become comfy with a particular fantasy they or their partner might have. Pornography can reboot a couple's sex life. It can offer you ideas, or help you connect with what turns you on.
Pornography can reboot a couple's sex life. It can offer you ideas, or help you contact what turns you on. Porn can provide you there at best, or disgust you at worst. Everything depends upon what you select to watch. With the schedule of porn online, it's possible to sample adequate 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 just a victim of bad porn 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 become a compulsive audience. In this case, it's not the porn that's the issue; 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 first. There are some who pick to perform due to the fact that they like sex a lot and they consider it a terrific way to make 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 mental health will deal with some drawbacks from this work. Our culture takes in porn at record numbers, however the ladies who carry out are still judged roughly.
I'm uncertain the male entertainers get out entirely unharmed either. While they might not be judged as roughly as the women, eventually they're viewed as freaks who make their living with their anatomy. John Holmes's fate is the supreme cautionary tale.
Perhaps if we weren't still so taken in with guilt and embarassment about sex, neither watching nor carrying Home page 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?
