Pornography is indeed destructive to men and women alike. While it is not prostitution in the sense that you are paying the person for engaging in sexual service in person, in a way it is indeed paying a porn star for their services or the companies that produce this "material". That is why I have used the term "cinematic prostitution" in this context.
Biblically speaking if one looks at a person with lust, not love, but lust in their heart, they are committing adultery. Such can be found in the words of Jesus in the Sermon on the Mount:
"Matthew 5:27 “You have heard that it was said, ‘You shall not commit adultery.’[e] 28 But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. 29 If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. 30 And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell."
It is not just porn with real people, be it straight or gay, that is atrocious, hentai, yaoi and yuri and other material similar is just as immoral. It doesn't matter if the person is real or not, using them as a means to slake your lust is dangerous and desensitising.
Let YHWH, Father, Son and Spirit give us all the grace to see how shameful sin is and repudiate it. Amen.
