Human Sexuality – Chapter Three – Physiology of Sexual Responses
- EPOR Model: Masters and Johnson’s approach to explaining sexual response ( Excitement, Plateau, Orgasm and Resolution ) .
- Excitement Phase: First physical changes of sexual arousal
- Plateau Phase: Sexual arousal levels off and remains at an elevated level of excitement.
- Orgasm: Sexual excitement and pleasure reach a climax.
- Resolution Phase: sexual structures return to unaroused state.
- Aphrodisiac: Mythical substances thought to enhance sexual arousal and desire
- Vasocogestion: Swelling of erectile tissues due to increased blood flow, because of sexual arousal.
- Sex Flush: Darkening of the chest area that occurs in some people during sexual arousal.
- Tenting: Widening of the inner two-thirds of the vagina during sexual arousal.
- Multiple Orgasms: More than one orgasm at short intervals as sexual stimulation occurs without a refractory period in between.
- Emission: Buildup of sperm in urethral bulb just prior to traveling through urethra.
- Ejaculatory Inevitability: Point where expulsion of semen is imminent and reflexive, cannot be stopped.
- Expulsion: Contraction of pelvic muscles that force semen through urethra and out of the body.
- G-Spot: Some women spot on the upper wall of the vagina, causes enhanced sexual arousal and orgasms.
- Refractory Period: Period of time between orgasms when person is unable to become aroused.
- Kaplan’s Three-Stage Model: Alternative to Masters and Johnson’s theory ( Desire, Excitement and Orgasm ).
- Hypoactive-Sexual Desire: Persistently low level of desire for sexual activities/sexual fantasies.
- Erotic Stimulus Pathway Theory: Model of sexual response based on psychological and cognitive stages of Seduction, Sensations, Surrender and Reflection.
