Female Sexual Response
Vagina, uterus during sexual response cycle
The outer labia becomes enlarged
The outer third becomes narrower which creates the orgasmic platform. This is cause by
vasocongestion.
Women don’t have a point of no return.
Women don’t have a refractory period
o Multi-orgasmic
Results of the Masters and Johnson Research
Clitoral orgasm: all orgasms are physiologically similar and triggered by clitoris.
Multiple orgasm a series of orgasms occurring within a short period of time.
4 phases observed in individuals of all sexual orientations (differences observed only in
way of being sexual: same sex couples more sensual, less genital/intercourse focused,
longer excitement stage.
Retrograge ejaculation: when ejaculation happens in the bladder.
Other Findings “Post-M&J”
Male ejaculation and orgasm are separate processes.
o Erection = vasocongestion
o Ejaculation = nerve muscular
75% of women need clitoral stimulation for orgasm reflex.
o Only 8-18% of women reliably have orgasm with just PVI.
G-spot and female ejaculation (expulsion)
o It’s not a spot it is a region.
o Back spot of the clitoris; it is a clitoral complex.
o When pressure is put the vaginal wall. Having that stimulated can lead to orgasm.
o The smaller quantity comes from the skene gland. The larger quantity (“squirting”) is
from the urine.
Multiple orgasm experience in males
Post-orgasmic sensitivity of the clitoris.
Psychosocial Aspects of STIs
The number 1 most reportable STI is chlamydia.
Gonorrhea is on the rise.
Reportable vs. Unreportable STIs
o Reportable STIs are the one that have been deemed a higher level of risk undiagnosed.
They are HPV, herpes, trichomonas, and human t-lymphotropic virus.
At least 90% of people will have HPV one in their lives.
