If you believe Jesus, even looking at a woman with lust in your heart is equivalent to full-on adultery, so no tiers. Many Christians actually believe that and, for example, would treat discovering a partner watching porn as if they’ve discovered the partner cheating.
My understanding is that anal and oral are “wrong” in the same way masturbation is, it’s spilling your seed outside of sex for procreation.
But like, clearly a tier better than premarital sex so…
They’re both considered sodomy
