The Sexy Science of
Fifty Shades of Grey
Joanna Wilson, D.O.
Board-Certified Internal Medicine
Clinical Associate Professor of Medicine,
Texas Tech Health Sciences Center
“A rich, handsome man
charms a young innocent
with lavish gifts and bold
declarations of desire. With
a smoldering gaze, he melts
her insides, turns her legs
to jelly and paralyzes her
subconscious, paving the
way for hot sex scenes
while she attempts to crack
his steely veneer.”

TAKING CONTROL
Fantasies
• Normal
– Help turn off the parts of the brain associated with
stress and anxiety
• Women are heteroflexible
– Sexual attraction to women is common in
heterosexual women
• Erotic novels are more arousing to women than
pictures
• Promote exploring different aspects of self and
partner
Snowden, Gray. Archives of Sexual
Medicine
• Restraint, sensory stimulation, role-playing, and a
variety of interpersonal dynamics
• Power Exchange
“Physical manifestation of psychological surrender.”
PAIN IS IN THE EYE OF THE
BEHOLDER
Endorphins: Anastasia’s Anesthesia
• Attenuation- pain perception can be reduced
and nerves can be desensitized
• Endorphins- released by painful stimuli and
orgasms and mimic morphine to reduce pain
Swedish vs. Deep Tissue: Your choice
• Pain thresholds vary person to person
• Interpretation of pain as pleasure may be a
variable of neuronal wiring or provide
psychological relaxation for some people
Timing is everything
• Sexual arousal encourages acceptance of
smells and fluids normally considered
offensive
• Lack of sufficient arousal upon exposure to
offensive substances augments feelings of
repulsion

VERY PERSONAL TRAINING
Why did Christian insist on exercising?
• The pelvic floor muscles which control urine
also contract during orgasm
• Strong muscles prevent urine leakage and
allow more intense orgasms
Pelvic Floor
Kegel Exercises
• Find the right muscles. To identify your pelvic floor
muscles, stop urination in midstream.
• Perfect your technique. Tighten your pelvic floor muscles,
hold the contraction for five seconds, and then relax for five
seconds. Try it four or five times in a row. Work up to
keeping the muscles contracted for 10 seconds at a time,
relaxing for 10 seconds between contractions.
• Maintain your focus. For best results, focus on tightening
only your pelvic floor muscles. Be careful not to flex the
muscles in your abdomen, thighs or buttocks. Avoid holding
your breath. Instead, breathe freely during the exercises.
• Repeat 3 times a day. Aim for at least three sets of 10
repetitions a day.

They won’t get lost,

THE CLITORAL
COMPLEX
The tip of the iceburg
• Clitoris has 8,000 sensory nerve fibers (more
than anywhere else in the human body and
nearly twice the amount found on the head of a
penis)
• The glans is connected to the body or shaft of the
internal clitoris, which is made up of two corpora
cavernosa wrapped around the vagina
• The corpus cavernosum also extends further,
bifurcating again to form the two crura. These
two legs extend up to 9cm, pointing toward the
thighs when at rest, and stretching back toward
the spine when erect
Orgasm 101
• Direct or indirect stimulation of clitoral tissue
induces orgasm
• Vaginal penetration tugs at clitoral tissue
• Some positions are better than others at
achieving sufficient clitoral stimulation
Location, Location, Location
• Distance of clitoris to vaginal opening is one of
the determinants of a woman’s ability to
orgasm during penetration
WHAT DO BREASTFEEDING MONKEYS
AND HUMAN ORGASMS HAVE IN
COMMON?
Oxytocin: A Big, Warm Chemical Hug
• Released during breastfeeding and promotes
uterine contractions and bonding
• Released during non-sexual touching of
romantic couples and lowers blood pressure
and promotes a sense of well-being
• Released during orgasm to promote a sense of
intimacy and relaxation
Bonding (not bondage)
• Great sex is not about technique, but about
feeling an emotional connection
• Generating bliss in the partner, and not
focusing on generating an orgasm

• 1800’s: Physicians treated common ailments (anxiety, depression,
aggression, hysteria, muscle aches) with weekly sessions of induced
‘paroxysms’

1880: Battery-operated vibrator by British physician Joseph
Mortimer Granville and manufactured by the Weiss Company

1920’s: Vibrators began to appear in pornography, giving them a social
stigma
– Nail buffers, back scratchers or vacuum attachments?

• Penetration
• Testosterone
• Arousal

Did Anastasia ever keep her
underwear dry?
• Vaginal lubrication
– Ingredients: pyridine, squalene, urea, acetic acid,
lactic acid, complex alcohols (including
cholesterol), glycols (including propylene glycol)
ketones, and aldehydes
• one third of women produce short-chain aliphatic acids
(a pungent class of chemicals which other primate
species produce as sexual-olfactory signals)
– Altered by: vaginal bacteria presence and species
(natural and probiotic use,) estrogen status, and
diet
The secret ingredient: pheromones
• “odorprints” in genital
discharge, sweat, and
saliva
– Contain immune system
identifiers
– Prevent inbreeding with
those with similar
pheromones and promote
attraction to those with
different ones
– Blocked during OCP use
affecting attraction

From slugs to vaginas
• Rabbit vaginas used for testing vaginal
chemicals, but slugs were better
• 5 consecutive days of exposure - Mucus
production discriminates between nonirritating and mildly irritating
• The slugs reported:
– Replens is mildly irritating
– KY is moderately irritating
– Nonoxynol-9 is severely irritating

Learnin’ Lubes
• Glycerol concentrations increase vaginal
secretions during sexual arousal
– Intensity of secretions is due to the osmotic
gradient of the compound (ie, glycerin, propylene
glycol)
• Highly hyperosmotic lubes (Astroglide) have
been shown to cause sloughing of the lining of
the colon and cervix and increase chance of
STD infection
