Being a Christian, I agree Jesus said not to lust in your heart, but I don't think it is what people think. I don't think it's wrong to have certain thoughts, but the parable was saying it can lead to evil if it gets out of control. Anyway, though, I would avoid porn, nonetheless, cause I believe it is full of witchcraft. Basically, it's a toxic environment spiritually. Who would argue otherwise?
I don't see anything wrong with porn. It ultimately depends on how a person consumes porn. I and my partner occasionally watch porn to learn and spice up our sex life. It is people that consume porn for mastubation that Las made the porn industry to seem like it is bad.
