What does the COVID vaccine have to do with anything?
Also, I have a book recommendation on the subject of pornography that may soften your self-condemning attitude. Check out Samuel Perry's Addicted to Lust: Pornography in the Lives of Conservative Protestants. The book is written strictly from a sociological perspective (i.e., it's not a religious book), which I actually found insightful, revealing, and refreshing. The book includes non-judgmental interviews with many people struggling with your very situation and you may get some useful insight into what you're thinking and feeling and what to do about it. And DEFINITELY read it before you start getting into Christian anti-porn literature.
If you don't want to spring for the book, I can share my electronic copy, too. I highly recommend it.
I highly recommend Samuel Perry’s Addicted to Lust.
In his (and my) opinion, the addiction paradigm of porn viewing and masturbation does more harm than good. It leads to greater compulsivity and pathology. And isn’t really an orthodox attitude. We aren’t sexual exceptionalists. Passions are passions. We fight them together as something common to man and woman.
