The sexual response cycle has four phases. The first phase is excitement. During this phase both men and women will experience things like nipple erections, increased muscle tension, increased heart rate and breathing and increased blood flow to the genitals.
For women, their clitoris, labia minora and vaginal walls begin to swell and vaginal lubrication begins. Their uterus and breasts also become engorged. For men, their testicles begin to swell and they begin secreting a lubricating liquid as well. Depending on the age of the male, getting an erection may happen faster for younger men as opposed to older men. Also, depending on the amount of stimulation the penis is receiving, the erection can come and go. The second phase is plateau. The plateau phase in preparing your body for orgasm.
Like in phase one, both men and women’s heart rate and breathing continue to increase as well as muscle tension. With the phase one changes intensifying, the women’s clitoris now becomes highly sensitive and retracts to avoid direct stimulation and the vagina continues to swell. Their uterus also becomes fully elevated. The men’s testicles now withdraw up into his scrotum to prepare for ejaculation and their coronal ridge increases in circumference. Once again, depending on the age of the male the plateau phase may be shorter for a younger male and longer for an older male.
The third phase is orgasm. As their heart rate and breathing continued to increase, it is now at their highest rate. Both men and women will start to have involuntary muscle contractions. Their contractions both take place in 0.8 intervals. The woman will have these muscle contractions in their vagina and even their uterus has rhythmic contractions. Some women have a fluid come from the urethra, not urine, during sexual stimulation. Men will have these muscle contractions at the base of the penis resulting in the ejaculation of semen.
Some men can experience retrograde ejaculation which means they feel like they are ejaculating but nothing is coming out because it is going into their bladder. The fourth and last phase is resolution. The resolution phase is when the body starts to return to normal and the swelling starts to go down. Their heart rate, breathing and blood pressure return to normal levels. For women, they may return to the orgasm phase and experience multiple orgasms.
They do not go through a refractory phase. As for men, they need time to recover after having an orgasm. This recovery period is called refractory period and the length of this time is different for everyone.
Some men report having multiple orgasms but it is very unlikely and thought to be another sexual response cycle happening right after another. Unlike the previous phases, it will take a younger male longer to lose his erection as oppose to an older male. MedicineNet. (2008).
