What Most Women Don’t Know About Their Own Anatomy | Sally Greenwald, M.D.

Many women and their partners lack fundamental knowledge about female anatomy, particularly the clitoris's internal structure and its role in pleasure, highlighting a significant gap in sex education.

• Most women are unaware of the full internal anatomy of the clitoris beyond its visible tip.

• Only about 10% of women can orgasm solely from internal G-spot stimulation or penetrative intercourse.

• Understanding individual anatomy and open communication with partners are crucial for enhancing sexual pleasure.

Most women possess limited knowledge about their own sexual anatomy, especially regarding the internal structures of the clitoris, such as the vestibule and crura, beyond the visible tip. This anatomical literacy gap extends to partners and contributes to difficulties in achieving orgasm through intercourse alone. Addressing this requires improved, anatomically accurate sex education and open communication about individual pleasure points and techniques.

Female Anatomical Knowledge

• 00:00:36 Many women exhibit a surprising lack of knowledge about their own bodies, particularly the intricate details of the clitoris, extending beyond the visible tip. While aware of the clitoral hood, most are unaware of the internal 'vestibule' and 'crura' which are bulb-like and wishbone-like structures with numerous nerve roots that engorge with blood flow, significantly contributing to pleasure and potential asymmetry in sensitivity.

The G-Spot and Orgasm

• 00:03:25 The 'G-spot' refers to an internal branch of the clitoris located along the anterior vaginal wall, roughly a third of the way in, which becomes rugated and engorged when aroused. Stimulation of this area can induce a sensation of needing to urinate, and while only about 10% of women can orgasm solely from this internal stimulation, education can increase this number. It also offers an alternative pathway for pleasure, especially as women age, due to its better blood supply compared to the external clitoris.

Intercourse and Orgasm

• 00:05:53 Less than 10% of women can orgasm solely through penetrative intercourse without additional external clitoral stimulation, making it a normal experience for the majority not to achieve orgasm this way. The likelihood of orgasm from intercourse is often related to the distance between the clitoris and the vaginal opening; a shorter distance (less than one inch) makes it more probable. For the 90% who don't, achieving orgasm typically involves identifying optimal positions, manual stimulation, or introducing vibrators to stimulate the external clitoris.

Educating Partners

• 00:07:47 Many male partners lack understanding of female anatomy, but most genuinely desire their partners' happiness. Providing men with a descriptive 'roadmap' of female anatomy, including the clitoris's internal structures and asymmetry of pleasure, can significantly enhance their ability to facilitate pleasure. Communication is key, and resources like 'Sex Talks' and 'OMGYes.com' help couples discuss and explore sexual anatomy and pleasure effectively.
