=== Fringe theories ===

Brody Costa et al. suggest that women's vaginal orgasm consistency is associated with being told in childhood or adolescence that the vagina is the important zone for inducing female orgasms. Other proposed factors include how well women focus mentally on vaginal sensations during penile-vaginal intercourse, the greater duration of intercourse, and their preference for above-average penis length.<ref name="Brody, Weiss">{{cite journal |title = Vaginal orgasm is associated with vaginal (not clitoral) sex education, focusing mental attention on vaginal sensations, intercourse duration, and a preference for a longer penis |journal = [[The Journal of Sexual Medicine]] |pages = 2774–81 |date = August 2010 |pmid = 19732304 |doi = 10.1111/j.1743-6109.2009.01469.x |volume = 7 |issue = 8 |vauthors = Brody S, Weiss P }}</ref> Costa theorizes that vaginal orgasm is more prevalent among women with a prominent [[tubercle of the upper lip]].<ref name="Brody, Costa">{{cite journal |title = Vaginal orgasm is more prevalent among women with a prominent tubercle of the upper lip |journal = [[The Journal of Sexual Medicine]] |date = June 2011 |pmid = 21676178 |doi = 10.1111/j.1743-6109.2011.02331.x |volume = 8 |issue = 10 |pages = 2793–9 |vauthors = Brody S, Costa RM }}</ref> His research indicates that "[a] prominent and sharply raised lip tubercle has been associated with greater odds ([[odds ratio]] = 12.3) of ever having a vaginal orgasm, and also with greater past month vaginal orgasm consistency (an effect driven by the women who never had a vaginal orgasm), than less prominent lip tubercle categories." Lip tubercle was not associated with social desirability responding, or with orgasm triggered by masturbation during penile-vaginal sex, solitary or partner clitoral or vaginal masturbation, vibrator, or cunnilingus.<ref name="Brody, Costa" />

An empirical study carried out in 2008 provides evidence for Freud's implied link between the inability to have a vaginal orgasm and psychosexual [[Defence mechanisms|immaturity]]. In the study, women reported their past month's frequency of different sexual behaviors and corresponding orgasm rates and completed the Defense Style Questionnaire (DSQ-40), which is associated with various [[Psychopathology|psychopathologies]]. The study concluded that a "vaginal orgasm was associated with less somatization, dissociation, displacement, autistic fantasy, devaluation, and isolation of affect." Moreover, "vaginally anorgasmic women had immature defenses scores comparable to those of established (depression, social anxiety disorder, panic disorder, and obsessive–compulsive disorder) outpatient psychiatric groups." In the study, a vaginal orgasm (as opposed to a clitoral orgasm) was defined as being triggered solely by penile–vaginal intercourse.<ref>{{cite journal |title = Vaginal orgasm is associated with less use of immature psychological defense mechanisms |journal = [[The Journal of Sexual Medicine]] |pages = 1167–1176 |date = May 2008 |doi = 10.1111/j.1743-6109.2008.00786.x |pmid = 18331263 |author1 = Brody S |author2 = Costa R.M. |volume = 5 |issue = 5 }}</ref> According to [[Wilhelm Reich]], the lack of women's capacity to have a vaginal orgasm is due to a lack of [[orgastic potency]], which he believed to be the result of culture's suppression of genital sexuality.<ref>Reich, Wilhelm (1984) Children of the Future: On the Prevention of Sexual Pathology. New York: Farrar Straus and Giroux, footnote on p. 142: "1949: The statement that the girl's clitoral masturbation is normal is also due to the then prevalent psychoanalytic concept that the little girl had no vaginal genatility. The lack of vaginal genatility was later shown by sex-economy to be an artifact of our culture, which suppresses genitality completely and instills castration anxiety not only in the boy but also in the girl. This creates a true secondary drive in the form of penis envy and predominance of clitoral genitality. Psychoanalytic theory mistook these artificial secondary drives for primary, natural functions."</ref>
