Lecture 3 - Wednesday March 28
SEXUAL DYSFUNCTIONS (ego dystonic) - variations in someone's sexual experience. All
dysfunctions are diagnosed when the person has distress about what’s going on. If the person
identifies as asexual or celibate, it doesn’t bother them so it is not a diagnosis.
Diagnosed only when the person does not have some sort of medical condition or substance
that they are taking that could otherwise explain what is going on. They are not diagnosed when
the person is having relationship distress with their sexual partners.
These people are unhappy because they desire sex less often than they would like to. In both
cases, the person is not as interested in sex as they want to be.
1. Male Hypoactive Sexual Desire Disorder
○ Persistent lack of interest in sexual activity
○ Causes distress
○ Hypoactive means an inhibition of activity
2. Female Sexual Interest/Arousal Disorder
○ Sexual interest
i. absent/reduced interest in sexual activities, thoughts, fantasies
ii. Unreceptive to a partner’s attempt to initiate sex
iii. Absent or reduced genital sensation during sexual activity
iv. Causing clinically significant distress
v. a woman can have sexual interest/arousal disorder just due to low
sexual arousal with a normal level of sexual desire
3. Erectile Disorder - the male sexual arousal disorder. Man has difficulty maintaining
erection during sexual activity
○ Marked decrease in erectile rigidity
i. Penis gets hard but not hard enough
○ Causes distress
4. Delayed Ejacution (men) - disorder in the amount of time it takes a man to reach
orgasm.
○ Infrequent or absent ejaculation
○ Period of time (plateau) is longer than he wants
i. Plateau is the phase before orgasm where the male would ejaculate
○ Causes distress
5. Female Orgasmic Disorder - the woman has delay, infrequency of or absence of orgasm
○ Reduced intensity of orgasmic sensation
○ Causes distress, unhappy about it
6. Premature/Early Ejaculation (men) - their orgasm phase comes way too soon in the
sexual response cycle.
○ Occurs within 1 minute following vaginal penetration.
i. This can be in a heterosexual or homosexual situation
○ Occurs before the man wants it to
○ Diagnosis for men and not women because men have a longer refractory period
(can’t be stimulated again for sexual arousal)
