In women, the most common way to achieve orgasm is by physical sexual stimulation of the clitoris; general statistics indicate that 70–80 percent of women require direct clitoral stimulation (consistent manual, oral or other concentrated friction against the external parts of the clitoris) to achieve orgasm,[1][2][3][4] though indirect clitoral stimulation (for example, via vaginal penetration) may also be sufficient.[5][6] The Mayo Clinic stated, "Orgasms vary in intensity, and women vary in the frequency of their orgasms and the amount of stimulation necessary to trigger an orgasm."[7] Clitoral orgasms are easier to achieve because the glans of the clitoris, or clitoris as a whole, has more than 8,000 sensory nerve endings, which is as many (or more in some cases) nerve endings present in the human penis or glans penis.[8][9] As the clitoris is homologous to the penis, it is the equivalent in its capacity to receive sexual stimulation.[10][11]
One misconception, particularly in older research publications, is that the vagina is completely insensitive.[12] However, there are areas in the anterior vaginal wall and between the top junction of the labia minora and the urethra that are especially sensitive.[13] With regard to specific density of nerve endings, while the area commonly described as the G-spot may produce an orgasm,[14][15] and the urethral sponge, an area in which the G-spot may be found, runs along the "roof" of the vagina and can create pleasurable sensations when stimulated, intense sexual pleasure (including orgasm) from vaginal stimulation is occasional or otherwise absent because the vagina has significantly fewer nerve endings than the clitoris.[16][17][18] The greatest concentration of vaginal nerve endings are at the lower third (near the entrance) of the vagina.[14][16][19][20]
