The Complexity of the Catholic View of Salvation

Protestants trade more obligations for more confusion. You have to avoid mortal sin just as Protestants do by not engaging in grave violations of the Ten Commandments. Can I be saved if I use IVF or donate my sperm? What if I'm like that recent guy in the Netherlands who donated his sperm 500 times? As a Christian, can I look at AI pornography and lust after an image that's not a real person?
