I think you will have to be more specific in what you are thinking here, because we do not go to confession for things that are natural to human nature-- I am eating a sandwich right now, that is something normal and it isn’t a sin.
**Masturbation is a completely natural human urge/function. Toddlers discover it, for goodnes sake. We are built to be sexual beings. How does being a normal human with an urge that is built into us constitute not loving God?
It is human nature and the nature of the mind to think thousands of different thoughts, to want or desire something, to want to be comfortable, etc. Yet if we even think of committing adultery, it’s just as bad as actually doing the act? How is this reasonable?**
Well, no. God made us in perfect holiness. Our original parents sinned against God and the result is fall human nature, not human nature as God created it.
**If God made us in ‘perfect holiness’, then we would have been perfectly holy. We are not. We are human, with both goodness and evil in us. **
There are 10. We transgress the 10 in many ways.
Well, several people have already told you that the website you are reading has no endorsement from the Church and cannot be taken as Church teaching.
