It seems to me that God is much more concerned with what happens in our board rooms than in our bedrooms. Billions on this planet live in poverty. Most Americans have no awareness of how money is really distributed in our country.
Our faith clearly states concern for the poor and economic justice is central to our faith.

Here are three quotes from the Catechism:

“There also exist sinful inequalities that affect millions of men and women. These are in open contradiction of the Gospel” (CCC #1938).

“Solidarity is manifested in the first place by distribution of goods and remuneration for work. It also presupposes the effort for a more just social order…” (CCC #1940).

“The equal dignity of human persons requires the effort to reduce excessive social and economic inequalities” (CCC #1947).

That said, sex is not unimportant and it’s power always grasps us by nature of our human weakness. Sex often leads to social inequalities as in issues of Human Trafficking and Pornography. So we should watch our sinful behavior in all matters and strive to live lives of holiness in all matters, not merely one over another.
