You're saying that you think Christians don't feel anxious about sex because they are taught to abhor sex outside of marriage?
I think that is a weak reframing of the breadth of sex, and that sex for the supermajority of American people, in and out of the church, is pre-marital.
I think young Christian boys are taught that sexual fantasy and pornography is the same as adultery, a defilement of the temple that is their body. I think one example that's brought up along these lines of narrative is a story of direct divine punishment for the spilling of seed. I think Protestant and non-denominationals with sizeable youth groups form little sexual discussion groups, especially for boys, where they vent their sexual guilt with regards to their fantasy of the day or how they masturbated. I think American Christian parents are ever anxious about government discussion of sex, and that they backwardly expend finite energy to make it a political battle point. And I think American Christian culture is as much about the implicit as it is about the explicit.
But somehow your choice framing of the discussion is that Christians don't feel dirty about sex because they are explicitly taught that only sex outside of marriage is dirty.
Young boys and girls in the church learn the anxiety of the community and their parents first, and then they listen to the belief structures to justify that anxiety.
A straw man, by the way, is a misrepresentation of someone else's discussion, and not actually a logical fallacy at all. It is by definition outside of logical purview. Most people would be better off not ever hearing about logical fallacies, because it gets in the way of quality thinking.
Anyways, I want to make one last point about American Christians expending their precious, finite energy in politics. I say that there are 3 high consensus Christian political issues in America, in order of strength: (1) abortion, (2) homosexuality, and (3) sex education in school. The latter is the weakest, and mostly in state-level politics, but there it is brutally fought. Notice the theme of these 3 issues?
It's really kind of silly that these are the highest consensus issues for American Christians. Um, not poverty, right? Or injustice in the police system, and classism and racism in America? Yes. Let's discuss abortion, homosexuality, and sex education in schools (condoms detract from abstinence!).
