Right, there's a popular idea that Christianity is somehow anti-sex, but that's not really accurate if you look closely at the tradition itself. The Bible doesn't condemn sex, in fact, books like Song of Songs celebrate it in pretty vivid terms (just to name an example though one could dig up much more..).
What Christianity actually critiques is sex outside of marriage. The reasoning is that sex is viewed as the most complete form of love between two people, and so it belongs within the lifelong commitment of marriage. Even then, it's worth noting that sex isn't at the center of Christian moral teaching. "Sins of the flesh" are taken seriously, but they're considered less grave than sins like pride or cruelty, something C. S. Lewis explains very clearly.
It's less about being "anti-sex" and more about believing that something so powerful deserves a proper framework.
We can argue about the moral framework of Christian values, of course and many have, thoughtfully, but it's important to at least critique what Christianity actually teaches, rather than a caricature of it.

You were on a good track, until that sentence.
There are multiple sects of Christianity that criticize sex for many other contexts. You may be somehow unaware of this, but homosexual pleasures are disapproved by some churches.
Historically, that's still quite wrong. The Church consistently taught (at least in the West, since circa 400 A.D.) that total abstention was required of their holy leaders.
Interesting perspective. But this is actually what Protestant Christians believe: https://ca.thegospelcoalition.org/columns/ad-fontes/5-surpri...
