At no point in history has women's sex (or "health") experts been helpful to literally anyone, and are responsibile for probably more failed relationships than fixed by a factor of 10 to 1.

That hasn't changed since Cosmo teaching girls to tug on your ballsack to now with them trying to make her cheat on you, and it never will. Because women hate other women's success, and their advice is always built to ruin them under the guise of "help."
