Sisestusfaas

Sisestusfaas refers to a phase in the sexual response cycle, specifically the initial stage of sexual arousal. During this phase, physiological and psychological changes begin to occur in preparation for sexual activity. These changes can include increased heart rate, blood pressure, and respiration, as well as vasocongestion, which is the engorgement of blood vessels in the genital and pelvic areas. For males, this often manifests as penile erection, while for females, it can involve clitoral engorgement and vaginal lubrication. Psychologically, individuals may experience heightened awareness of sexual stimuli, increased desire, and a general sense of anticipation. This phase is characterized by a gradual buildup of arousal and can vary in intensity and duration from person to person. It serves as a precursor to subsequent stages of sexual response, such as plateau, orgasm, and resolution. Understanding the sisestusfaas is important in comprehending the overall human sexual response.
