More Frequent Vaginal Orgasm is Associated with Experiencing Greater Excitement from Deep Vaginal Stimulation
Abstrakt
Recent research has shown that stimulation of the clitoris, distal vagina, and proximal deep vagina/cervix is conveyed through different peripheral nerves (Komisaruk et al., 2011) to different brain regions (Komisaruk & Whipple, 2005). The orgasm induced by clitoral stimulation and penile-vaginal intercourse differ in important ways (Jannini et al., 2012).
The aim of this study is to examine the association of vaginal orgasm consistency (VOC)with 1.) sexual arousability perceived from deep vaginal stimulation (compared with middle and shallow vaginal and clitoral stimulation), and 2.) whether vaginal stimulation was present during the woman's first masturbation. A sample of 75 women (aged 18 - 36) provided details of recent VOC on 5 point scale (from 1 - never to 5 - 75% to 100%), age, sexual arousability from deep vaginal stimulation, middle vaginal stimulation, shallow vaginal stimulation (vaginal entrance) and clitoral stimulation (rated on 7 point scale, from 1 - low to 7- high), and whether their lifetime first masturbation involved only clitoral stimulation, only vaginal opening stimulation, only deep vaginal stimulation, or both clitoral and vaginal stimulation.
Pearson correlations were conducted between VOC, age and sexual arousability during stimulation of four genital sites. VOC was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites.
VOC was also associated with women's first incorporating (or being exclusively) vaginal stimulation. The finding suggest 1.) stimulating the vagina during early life masturbation might indicate individual readiness for developing greater vaginal responsiveness, leading to adult greater VOC and, 2.) current sensitivity of deep vaginal and cervical regions is associated with VOC, which might be due to some combination of different neurophysiological projections of the deep regions and their greater responsiveness to penile stimulation.
