However, even in this case only the Bonaparte-derived discriminant function classified these women better than chance. To determine the comparability of the two samples they were compared on CUMD and height using independent t tests. Expert Database Find experts with knowledge in: The term vaginal orgasm has been used to describe the orgasm some women have when they are receiving stimulation only from penetration of the vagina. For women, contractions occur in the lower part of the vagina, in the uterus, anus, and pelvic floor.

What is cervical stimulation and is it safe?

Two subjects were dropped because it was not possible to determine whether these subjects experienced orgasm in intercourse with direct clitoral stimulation or from intercourse alone. The tissues deep inside become badly inflamed, and the pressure of intercourse causes deep pain. In this process the primary erogenous areas of the penis become the underside of the glans penis, where the frenulum connects the foreskin to the glans penis and, to a much lesser extent, the penile shaft. This view, that there is a mature and psychologically healthy form of female orgasm, has become less prevalent, but is still promoted more than years after Freud's proposals. Such problems might include ovarian cysts.

Clitoral variability compared with penile variability supports nonadaptation of female orgasm. The data sheets for coding contained only the answers to the questions described above and contained no other information about the subject, except the unique subject identifier assigned in the original study. Male data are adapted from Kinsey, Pomeroy, and Martin, and the female data are adapted from Kinsey, et al. It helps if we are consistent and as precise as possible when we use these terms. Studies of same and mixed sex twins could directly test the hypothesis that small differences in prenatal androgen exposure affect CUMD, with women with female co-twins having smaller CUMD measurements than would women with male co-twins. Whether this reflected an actual difference in the two samples or a consistent difference in how CUMD was measured cannot be directly determined from the methods described in the two articles. Data are shown for the samples combined and for the CUMD measurements of women in the Bonaparte sample experiencing autosexual orgasms.

See other articles in PMC that cite the published article. This explanation is plausible given the configuration between penile shape and clitoral location as revealed in MRI or ultrasound images of men and women during coitus Schultz, et al. The question remains unanswered as to why a minority of women routinely experience orgasm solely from sexual intercourse, whereas most women require other types of stimulation. Unresolved, however, is the different distribution of CUMD measurements in the two studies. However it seems likely that the Landis measurement may have included the clitoral glans, whereas the Bonaparte measurement, having been taken from the underside of the clitoral glans, did not. Possibly variation in prenatal androgens produces other genital changes, in addition to rostral migration of the genital tubercle, that influence the type of stimulation a women requires for reaching orgasm. Unfortunately, there are still some physicians and gynecologists who may not be very sensitive to a woman's concerns or see the problem as simply one of "needing to relax" or "not worrying.
