Sexual Response Cycle 2
Sex seems to be the one three letter word that has such a huge impact on life. Sex is an act, an
experience, and notion that has so many different views around the world on what is normal and
what is deviant. However, no matter where the people are, who the people are, or what gender
those people are, they all experience the same cycles during sexual encounters (Nevid & Rathus,
2005). This cycle is called sexual response cycle which consist of four stages or cycles (Nevid &
Rathus, 2005). The four stages are excitement phase, plateau phase, orgasmic phase, and
resolution stage (Nevid & Rathus, 2005). These stages may be hindered by a sexual dysfunction,
and cause a person not to be able to start or complete the sexual response cycle.
The excitement phase is characterized by vasocongestion (Nevid & Rathus, 2005).
Vasocongestion is the swelling of the genital tissue in the penis and around the vaginal with
blood, also swelling occurs in the nipples and earlobes (Nevid & Rathus, 2005). Vasocongestion
can occur in young males as soon as three to eight seconds from the time sexual stimulation first
occurs. In females this time may start after ten to thirty seconds after stimulation occurs (Nevid
& Rathus, 2005). The skin will also become flush, which is more predominant in women than in
men. Both men and women may experience erect nipples and an increase in heart rate and blood
pressure (Nevid & Rathus, 2005).
In the plateau phase of sexual response cycle, the arousal remains constant and somewhat
stable (Nevid & Rathus, 2005). During this phase, males’ penis head will turn a purplish hue and
show somewhat of an increase in circumference (Nevid & Rathus, 2005). His testes may increase
