>>835844Not that anon but in actual chivalric romance the knights do fuck. In the big kidnapping story of the time,
Lancelot, the Knight of the Cart, the queen is kidnapped for blackmail, and when Lancelot frees her, they do spend the night together. The sleeping with sword thing is from Tristram and Isoud, which does not include kidnapping. But they do fuck, although only later.
Infidelity is like the main focus of most chivalric romance. They sometimes do marry princesses, but mostly they make love to queens.
