Our reading
An editorial interpretation.
The speaker asks about sex supposedly planned for some point in the future, then stretches that future to ever again. The pointed wording makes continued intimacy sound uncertain. It can read as a complaint or warning, using a question about remembering plans to raise their possible disappearance.
