In 1924 a revolutionary research paper on the female orgasm was published in Europe under the pen name A. E. Narjani. But as it turns out, the real author was actually Princess Marie Bonapart, great-grandniece of Emperor Napoleon I of France and daughter of Prince Roland Bonaparte. After she married Prince George of Greece and Denmark in 1907, her official title became Her Royal Highness, Princess George of Greece and Denmark.
Sadly, the Princess suffered from what many women today still do – the inability to reach orgasm solely through vaginal intercourse. Defying the social mores of her era, she discovered she could reach orgasm through masturbation. While this led her to blame physiology and not psyche, it still left her deeply frustrated with her husband and eventual four other lovers. But the Princess refused to accept such fate as a permanent condition! Instead, she began some of the most revolutionary work of her time on female sexuality and anatomy while also embarking on her quest for orgasm by penetrative sex.
She first examined and interviewed 243 women. One by one she measured the distance between their clitorises and the vaginas, then compared the distance to their frequency and ease of orgasm. What she discovered was a direct correlation between the ability to orgasm through vaginal sex and the measurement of space between the vagina and the clitoris. She categorized the findings from her subjects in three ways: paraclitoridiennes (para meaning “alongside”), mesoclitoriennes (meso meaning “in the middle”), and téléclitoridiennes (télé meaning “far”).
Paraclitoridiennes were the fortunate ones. The space between their vaginas and clitorises measured less than one inch. For the 69% of her test subjects that fell into this category, vaginal orgasm was easier than ever to reach. However, similar studies conducted in modern times prove this statistic extremely high.
