Psychological Aspects of Human Sexuality
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
● Women don’t have a point of no return.
● Women don’t have a refractory period
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.
