I'm highly skeptical of this kind of flip advice from women - even professionals - towards men, just as I would be skeptical of advice from men given to women in areas where they have little or no relevant experience.

There's only so many ways you can tell your wife/gf/partner that you desire them sexually, need sex daily or nearly daily, cherish it, etc.

At a certain point, it becomes pathetic, which is poison to attraction. Eventually your only real option is to break off that piece of yourself, kill it dead, and give the rest over to stoicism. Take what you can get and move on, understanding that your needs won't be met. You're a man and that's part of the deal. Work on yourself, your hobbies, your career, your relationship with your children and friends, and just move on from the false hope that your partner will ever be on the same page.
