A vagina orgasm is by definition an orgasm occurring during vagina intercourse and definition states a vagina orgasm occurs only when the vagina is stimulated and nothing else. Our famous friend Freud himself finds the vaginal orgasm mature and the clitoral immature. He even goes as far as to imply that vaginal orgasm is for the married women while clitoral is for the unmarried women.
When some people inquire about the difference between a "clitoral" and a "vaginal" they need to understand that a orgasm lies more so in which body part is stimulated to achieve orgasm, not necessarily where you feel the orgasm. The clitoris has a central role in elevating feelings of sexual tension. During sexual excitement, the clitoris swells and changes position. The blood vessels through the whole pelvic area also swell, causing engorgement and creating a feeling of fullness and sexual sensitivity. Your inner vaginal lips swell and change shape. Your vagina balloons upward and your uterus shifts position.

We cannot discount one or the other. As we steer toward our next type of orgasm- the cervical orgasm. We find even less information. Yet do find noteworthy things to mention.
“A cervical orgasm is sometimes called the Master Stroke Technique in reference to the technique used in achieving this orgasm. Ironically, many women avoid penile contact with their cervix's because of fear of overeager men banging up against them, causing pain instead of pleasure. The scientific discovery of the cervix as an erogenous zone is very new (though the ancients knew about it centuries ago). It's an important acknowledgment, because until recently, the cervix was considered to be completely insensitive. Now it's known to be extremely rich in super-sensitive nerve endings. This stands to reason, since nature wants to direct the sperm toward the egg by drawing the penis as close in and tight as possible. Proper stimulation of the cervix can trigger repeated, deep, and powerful orgasms.
“The Master Stroke Technique has been described last because it's last in the top-to-bottom sequence of genital stimulation. It should also be performed last, after your partner is in total arousal and her vagina is most relaxed and receptive. This is when her cervix will be most sensitive to stimulation.”(2)
Now we have reached the climax: a type of orgasm that goes beyond Freud's definition….. The post-clitoral orgasm is a contextual understanding of the four types of orgasm that a woman is actually capable of achieving; the ability to physically experience a post-clitoral orgasm in which the woman achieves; clitoral, vaginal, cervical, and g-spot orgasms simultaneously.
