Certainly sexual relations is not a certain outcome of a romantic relationship, but it seems contrived to suggest that a romantic relationship is ordinarily unrelated to sexual attraction. The examples you quote take the discussion away from the ordinary, and away from the context in question: a married person engaging in an intimate romantic relationship with another.“Romance” doesn’t always have to lead to “sex”. It’s possible to have a romantic relationship without sex.
If a married man has his penis surgically removed (such as if it contained cancer cells) then he and his wife would still love each other. Or if two heteromantic asexual people (who can be romantically attracted to opposite genders but not sexually attracted to anyone) get married they’d still love each other even if they never had sex or only had sex for the purpose of pregnancies.
While Sex improves a romantic relationship, a romantic relationship can still exist without sex.
