The Plateau Phase

Characteristics of sustained tension and variability

The plateau phase should not be interpreted as a flat or static state, but as a period of sustained high sexual tension preceding climax. It is an intensification of the changes initiated at arousal.

At this stage, heart rate, blood pressure, and respiratory rate increase significantly in both men and women.

There is also generalized muscle tension (myotonia) which may affect not only the pelvis, but also the facial muscles, arms and legs. The duration of this phase is highly variable.

Some people transit through it rapidly, while others may remain in this state of high arousal for a prolonged time before reaching the threshold of orgasm.

In the clinic, it is common to find discrepancies in rhythm between partners; one may need a long plateau to build up the necessary tension, while the other becomes frustrated or gets ahead of himself. Understanding this variability is key to erotic synchronization.

Specific changes in female physiology

During the plateau in the female, crucial anatomical changes occur. The outer third of the vagina becomes massively engorged, creating what is known as the "orgasmic platform," which narrows the vaginal opening and increases friction and pleasure.

The uterus finishes rising into the abdominal cavity, and the clitoris retracts under its hood, becoming extremely sensitive to direct touch (which can sometimes be painful if sharply stimulated).

In addition, the change in coloration of the labia minora intensifies, turning from bright pink to deep red or wine (especially in women who have had children), indicating impending maximum vasocongestion.

The mammary areolas expand so much that they may give the impression that the nipples have flattened.

These signs are biological indicators that the body is ready for orgasmic discharge.

Pre-orgasmic changes in male physiology

In the male, the plateau phase involves a further increase in the diameter of the penis, especially at the crown of the glans penis, which may change color toward more purple tones.

The testicles reach their maximum elevation, sticking to the body, and may increase up to 50% of their usual size due to engorgement.

This testicular elevation is a physiological prerequisite for the force of ejaculation.

A distinctive phenomenon of this phase is the secretion of Cowper's glands, which produce a few drops of clear pre-seminal fluid at the tip of the penis.
