If the vaginal orgasm did not exist (as some sceptics claim), PE would never have become a problem. But it does. In truth, while the man has only one main “gateway” to pleasure, the woman has at least two - the vagina and the clitoris. Women, according to their own sexual experiences and also according to many scientific studies, can have an orgasm that is generated by the stimulation of the clitoris, vagina, or a combination of both. And there are those who claim the existence of a third type of orgasm derived from the stimulation of the cervix, but the percentage of women able to experience it is very low.
So, what are the undisputed differences between these two types of orgasms? The clitoral orgasm is the most commonly experienced, likely to be achievable by all women. The clitoris is exposed, can be stimulated easily and quickly, and once orgasm is reached, the body is pervaded by a sense of heat and electricity. Some women however, have a clitoris that is more sensitive than others and its stimulation can be experienced as irritating and causes discomfort rather than pleasure. The vaginal orgasm, instead, is much less frequently experienced (20-30%), and is linked to penetration during intercourse. Pressure and friction extended to an area of the front vaginal wall, identified as the much debated G spot, causes a more intense orgasm, characterised by a deep pulsating sensation.
The vaginal orgasm comes from a distinct erogenous zone and is not just a simple extension of the clitoris inside the vagina. Distinction between the originating areas of vaginal and clitoral orgasms is also supported by clinical observations. It has been observed using magnetic resonance imaging (MRI) during auto-eroticism, that differing sensory areas in the female brain are activated according to whether the orgasm is clitoral, vaginal or cervical.
