Viewing porn is not inherently harmful to guys or ladies. However I would use some caveats. There are people who probably should not view porn, like those with bad body image or those who have been sexually victimized. Depending upon your choice in watching, you can establish unrealistic expectations about sex or what individuals like or how you'll be anticipated to "perform." And seeing with someone requires real permission.
When none of these warnings are up, porn can certainly have advantages. Counselors sometimes recommend it to help individuals become 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 connect with what turns you on.
Porn 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. Everything depends on what you pick to view. With the availability of pornography online, it's possible to sample enough pornography quickly that you do not have to find yourself watching wall-to-wall hard-core sex if it's plot driven erotica that interest 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 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 harmful or beneficial to the entertainers, let's take women initially. There are some who choose to carry out because they like sex a lot and they consider it an excellent way to earn a living. Then there are those who are drawn to porn as a method of acting out subconscious psychological problems-- looking for daddy's love or penalty for being a bad girl. For lots of, it's probably a little of each. Even females with the best psychological health will face some disadvantages from this work. Informative post Our culture consumes pornography at record numbers, but the females who perform are still evaluated harshly.
I'm not exactly sure the male performers go out totally 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 regret and pity about sex, neither seeing nor performing in these movies would carry the weight it does. However then, perhaps we would not be so interested in them, either. If the fruit were not prohibited, would anyone care to take a bite?
