'Vaginal orgasm (as defined by women's orgasm triggered by penile-vaginal intercourse without concurrent clitoral masturbation by self or partner) is shown to exist through both physiological and psychological evidence. The strongest evidence comes from brain imaging work conducted by Prof. Barry Komisaruk. In a sample of spinal cord injured women (who thus had no connection from their clitoris to their brain), orgasm could be induced by deep vaginal-cervical stimulation. The orgasm was confirmed by both self-report and by brain imaging evidence.
The orgasm from deep vaginal-cervical stimulation was explained as relying on the Vagus nerve, rather than the other nerves through which the clitoral sensations would travel. Thus, orgasm triggered by deep vaginal-cervical stimulation is not dependent on clitoral sensation. In my recent paper with Prof Komisaruk, we showed in intact women that stimulation of the clitoris, lower vagina, and cervix activate different parts of the brain (as well as an overlapping region).Se også: Få 6 vilde orgasmer
Although it is often asserted in both the media and mainstream sexology that vaginal orgasm is rare, the best evidence using large nationally representative samples of women (in the Czech Republic and Sweden) is that the clear majority of women have had vaginal orgasm (as defined above).
In contrast to women who have only had orgasms from clitorally focussed activities, or even from clitoral masturbation during intercourse, women who have vaginal orgasms have (on average!) better psychological and physical functioning.
The psychological measures used in a wide variety of studies conducted in several countries include sophisticated indices of psychological development (attachment style and type of psychological defense mechanisms used), greater intimate relationship satisfaction, greater life satisfaction, greater sexual satisfaction, and greater satisfaction with their own mental health. Women with a history of vaginal orgasm are also less likely to eventually develop female sexual arousal disorder.

The physical differences include that women who have had vaginal orgasm have less musculoskeletal blockage (as revealed by less impairment of pelvic and vertebral rotation while walking), and have greater resting heart rate variability (a cardiovascular measure of self-regulation of not only the heart but also other psychological and physiological regulatory processes).Se også: Her er genvejen til g-punktet
Thus, denial of the existence of vaginal orgasm might undermine women's health and constitute malpractice (given the evidence noted above on health correlates of specifically vaginal orgasm).
A review of the health correlates (and in some few experimental studies, we can say effects in the hard scientific sense) of various sexual behaviours found that of the universe of sexual behaviors, there is only one that is associated with indices of better psychological and physical health: penile-vaginal intercourse (this is the one potentially reproductive sexual activity, and evolution does discriminate in rewarding different activities).
In addition to health differences associated with engaging in different sexual activities, there are health differences associated with different orgasm triggers. It is unfortunate that the prejudices common among many sexologists and sex educators have involved avoiding being specific about such health differences.
Beyond the health issues per se, there is also the scientific value of examining a connection between psychological development and response (or lack of response) to the one potentially reproductive sexual activity.
