Unit 3 Flashcards
Phases of Masters & Johnson’s Sexual Response Cycle
1) Excitement Phase
2) Plateau Phase
3) Orgasm Phase
4) Resolution Phase
Excitement Phase of M&J Sexual Response Cycle
Phase one
-Vaso congestion
-Myotonia
-Lubrication of Vagina
-Nipple Erection
-Erection of Penis
Vasocongestion
INC blood flow
-Nitric oxide present in sexual enhancers
Myotonia
INC muscle tension
Ability to achieve an erection can be effected by
-Alcohol consumption
-Stress
-Age
Hormones:
-Dopamine
-Oxytocin
-Testosterone
Plateau Phase of M&J Sexual Response Cycle
-Clitoris engorges & rises to under its hood
-Upper 2/3 of vagina expands
-Tightening of vaginal introitus
-INC blood flow (BF) to tip/glans of penis
-Cowper’s gland secrets pre-cum (contains sperm!)
Tightening of introitus info
Bulbospongiosus
-Is homologous to the muscles supporting an erection
Formation of Orgasmic Platform
Upper 2/3 of vagina expanding & tightening of introitus
Orgasm Phase of M&J Sexual Response Cycle
-Altered state of consciousness
*INC happiness & endorphin release
-Contraction of uterus (upsuck semen)
-Vaginal contractions
-Emissions Phase
-Expulsion Phase
Emissions Phase
Spilling of semen from urethra
-Ejaculatory inevitability - Its gonna happen
Expulsion Phase
Contraction of M prostate and urethra to expulse semen
-First happens frequently then a delay lengthens between each one
-Intensity INC
Resolution Phase of M&J Sexual Response Cycle
-Vasoconstriction
-M cannot be aroused for a refractory period
*Coolidge Effect
-F can go back into excitement phase
Coolidge Effect
Exposure to same partner INC refractory period
-DEC w/ new sexual partner
Criticisms of Masters & Johnson’s Model
-Doesn’t incorporate desire
-Doesn’t incorporate pleasure
-Required an orgasm history
Kaplan & Colleagues Model (1979)
Desire, excitement, and orgasm
-Excitement & orgasm phase = strength
-Controlled by ANS
-Vasodilation is a PNS response
-Myotonia is an SNS response
Criticisms of both Kaplan & Co. AND M&J Models
-Cultural & mood impacts not considered
-Dual control model - We live on a continuum
-Excitation and inhibition
*Inhibition may cause relationship issues
*Excitation is not adaptive and can cause riskiness and potential unwanted pregnancy or STI
-Orgasm isn’t focused on
-Daily diary reports
*Confusion of anger VS arousal
-Disgust
Autoeroticism
Self pleasure or arousal
-Masturbation, fantasies, erotica, ect

Missionary
Cowgirl

Side by side - Spooning sort of
-Good for those pregnant, plus sized, and fatigued
Mouth genital stimulation
Fallacio - blow job, don’t scrape
Cunnilingus - Vaginal mouth stim, more likely to cause an orgasm than coitus
-CAN transmit STI
69
Simultaneous mouth-genital stimulation
Anal intercourse
Sodomy - Penis or fingering anus
-Only use water base lube
-Relaxation is important for person receiving
-No evidence to cause O (orgasm)

Ejaculation and Orgasm info
Usually happen at the same time, but ejaculation can occur w/out orgasm.

-Socialization of M needing to be super horny
-F may be more sensitive (need less) to T
Sexual Interest Network (SIN) Parts
-Nucleus Accumbens
-Hypothalamus
-Amygdala
-Anterior Cingulate Cortex
-Excitory & Inhibitory Hormones
Nucleus Accumbens function in SIN
DA receptors (a LOT of dopamine present)
-Attention to things we like (insensitive salience)
Hypothalamus function in SIN
Motivation and hormone release
Amygdala function in SIN
Emotions center
Anterior (toward front) cingulate cortex function in SIN
Attention and environmental cues
-Those with ADHD have issues w/ this area’s function
Hormones at play in the SIN
-DA
-Norepinaphrine

-Natural opioids and cannabinoids - feels good
Pheromones VS Hormones
Hormones are released INSIDE the body while pheromones are released OUTSIDE of the body.
Vomeronasal Organ
Detect mates and pheromones
