Female Orgasm

Orgasm is a simple reflex response to sexual stimulation, and can occur as the result of a variety of sexual stimuli. The physical cycle of arousal, however, is always exactly the same. Though intensity of the experience may vary from woman to woman, and from time to time, and depend on the source of stimulation. The Americana sexologists Masters and Johnson have identified four phases of the orgasmic cycle: excitement, plateau, orgasm and resolution.

The excitement phase is brought about by sexual thoughts, emotional closeness and physical attraction. The body immediately reacts with an increase in general sensitivity and response to caresses.

The sexual organs become filled with blood, so that they swell both internally and externally. The vagina expands in length and width and the vulva swells a little. Both the clitoris and labia minora (inner lips of the vulva) fill with blood and may become darker in colour. The vagina begins to lubricate itself in readiness for sexual contact.

The plateau phase follows immediately. The sexual organs become extremely sensitive, responding to the caresses of lovemaking. The vagina expands to become about two inches longer than in the non-aroused state. It is at this point that intercourse may be taking place, and sensation by the narrowing of the outer third of the vagina, making it grips the penis more easily. Lubrication of the vagina continues, and all the muscles around the sexual organs become tense in a very pleasurable way. The breasts may swell and the nipples become erect, especially if they are touched. Breathing is deep, and there may be a light rash over the upper parts of the body.

The clitoris, which is the most sensitive of the female sexual organs and where all orgasms begin, is now fully erect. Just before orgasm, it pulls itself back inside the clitoral hood.

Orgasm may now occur. There will be a rush of extremely pleasurable sensation beginning at the clitoris and moving outwards into the whole body. The muscles surrounding the vulva, vagina and anus now go into a series of spontaneous rhythmic contractions, which are delightful indeed.

The resolution phase then begins immediately after orgasm. In it, the sexual organs return to a non-aroused state.  The volume of blood, which has engorged the sexual organs slowly, drains away back into the body. Sexual interest may be aroused again almost immediately, and one or more orgasmic cycles will recommence.
