1. Excitement: This is the initial phase, where sexual arousal begins and the body starts preparing for sexual activity. There is an increase in heart rate, breathing, and blood flow to the genitals, along with physical changes like nipple erection, vaginal lubrication, and penile engorgement.
2. Plateau: The plateau phase is the point where sexual excitement reaches its peak. The physiological responses intensify, and individuals may experience increased sensitivity and pleasure. The body may go into a state of muscular tension, with involuntary muscle contractions.
3. Orgasm: The orgasm is the climax of sexual activity. This is the phase of intense rhythmic muscle contractions in the pelvic muscles, accompanied by a sensation of pleasure and emotional release. Orgasms are often characterized by a release of sexual tension, involuntary vocalizations, and a brief loss of voluntary control.
4. Resolution: After an orgasm, the body enters the resolution phase. This is a period where the physiological responses gradually return to normal, and muscle tension decreases. The individuals' breathing, heart rate, and blood pressure settle down.
5. Refractory period: Following orgasm, there is a refractory period, during which individuals are generally unable to experience another orgasm. This period can vary in duration, from a few minutes to a few hours, depending on the individual and their level of sexual arousal.
6. Post-resolution: The post-resolution phase is the final stage, which occurs when the body has completely returned to its pre-aroused state. This is a period of relaxation, where the individuals' physical and emotional responses calm down, and they may experience feelings of contentment and closeness with their partner.
