I’m afraid this article is overly optimistic.

IMHO some people will never do what their partner wants, regardless of what such partner does, e.g.:

– People who have issues with sexuality (especially when they are resistant to work on it).

– People who have low libido (they may become willing to do “the deed”, but likely in a lukewarm way).

– People who have an egocentric or selfish attitude, hence what others want always come second to what they want.

I'm afraid that, when there's so little compatibility (or willingness), there will be no "magic" behavior that will solve the issues.
