What IS good, and how do we determine it?

This is incorrect. The book I quoted was written in 1929 before JPII was pope, by a man named Heribert Jone. Theology of the Body is a different book. True sodomy is defined by climaxing outside of the vagina, regardless of where exactly. That is still considered a sin.

I can't speak for the SSPX since I am not associated with them and know nothing about them.

I don't doubt the terms long predate The Theology of the Body Catholic_Lady but the fact remains that both Imperfect and Perfect Sodomy were sins that were to be confessed and refrained from preforming. Since The Theology of the Body heterosexual couples are no longer in sin if they engage in Imperfect Sodomy.

I know you're not SSPX, I simply tend to refer to their works fairly often when I'm debating Catholics since they're excellent reference works. For those who don't know the SSPX are an ultra conservative Catholic group who believe that Vatican II was not a valid council of the Catholic Church and all changes since that time are of the devil. For that reason they've got a very keen eye for "blasphemies" preformed by the mainstream Catholic Church and they're very helpful for me in finding points where the Catholic Church has done U-turns on doctrine over the past sixty years or so.

Prior to Vatican II I have to look elsewhere but for events after then they do make many valid points. I still think they're silly though, they claim to be loyal to the Pope but decry him as an infidel and some even pray for his death at the same time go figure.
