Bible and Christian beliefs aside, pornography is a dangerous tool of sexual predators. Porn perceives women as dirty whores that enjoy having male fluids spattered on them, enjoying swallowing male fluids, enjoying being treated like a whore during intercourse and enjoying being humilated to point where not only you can be satisfied but they whole process of being treated like some sex toy somehow made you climax. This includes lesbian porn, which undermines real lesbians with real relationships
Reality check: real women that respect themselves hate porn of all kind because once a man is addicted to porn, he perception of sex with a real woman is screwed. Therefore, whatever kind of mind a man has at the beginning, that is violent already, can be completely damaged into thinking of woman as just that : sex toys. This leads to rape and mistreatment of woman by strangers or their boyfriends. This also encourages spousal abuse. Pornography doesn't help someone's sex life, it hinders it.
Let's also mention the use of hentai, which is possibly more dangerous than live action porn because it used to lure children to a child molestors grubby hands.
