This orgasm may begin in the vagina and/or cervix, and expand from there. It can also remain focused the entire time in those areas. This orgasm is demonstrated when the vagina remains snug and the uterus does not elevate.
During the heightening of excitement, the vaginal opening becomes more lax and then bears down upon the arrival of an orgasm. The pelvic muscles and uterus, as well as the anus may also begin to contract. At the peak of the orgasm, anything inside the vagina being used for stimulation may be forced out by the strength of the contractions.
Because the vaginal/cervical orgasm involves the cervix, which is located further up inside the vagina, a long object inserted into the vagina that can reach the cervix may be more successful in reaching this type of orgasm. This would include a penis or dildo that is over 5 inches in insertable length.
It is interesting to note that during this type of orgasm, there is evidence that the mouth of the cervix will actually widen to admit the head of a penis, and create a suction generated by uterine contractions for the uterus to take in semen.
This orgasm usually takes longer to build, and is best achieved with rhythmic thrusting. Even more helpful is thrusting after being clitorally stimulated. Many women describe it as a pressure that grows and then explodes deep with in the vagina, quickly spreading intense, euphoric energy throughout the entire body.
This orgasm can release an intense emotional response as it provides women with a sense of being penetrated more than just physically, but also in an emotionally vulnerable sense.
To achieve this orgasm, you can use your fingers, sex toys and sexual intercourse.
