Human Sexual Response
Problems with doing sex research:
Many people are misinformed when it comes to sex. Those who struggle with their sex
lives rarely have mental/physiological issues. They simply have learned negative ideas
Myths and Fallacies:
“Males by divine guidance know what a woman wants and when she wants it”. This
leads to women lying to their man that they are doing a great job during sex to protect
their feelings and masculinity.
The search for aphrodisiacs (sexually exciting food such as raw eggs, chicken soup,
olives, peanut butter) but research shows that there are no known aphrodisiacs.
Penis Size: They argue that the smallest penis can do the job because once you go past a
certain area the woman’s vagina is insensitive.
Masturbation: part of selfawareness and exploration. Historically, it’s been associated
with blindness, insanity, etc. Young children are taught at a young age that it’s wrong to
touch that area. But as they reach adolescence, they start to explore.
Orgasm: By focusing on the time measure and how long it takes to orgasm, it interferes
with the pleasure of sexuality. Our culture gives us ideas of what it’s supposed to be like.
There’s a cultural script and when expectations don’t line up people fake it. Many
heterosexual couples share relatively the same common perspective and it limits the
endless ideas/creativity of what sex could be. Porn interferes. On a relating note, Masters
and Johnson’s view of the sex response was:
The excitement stage (slow buildup of fluids) > plateau stage (really excited) > orgasm
stage (physiological climax) > and resolution stage (a long or short time of really
enjoying the moment after).
Sex as a barometer of a good relationship is also a myth. Bad sex doesn’t equal to a bad
relationship or the reciprocity of it. You can have one without the other.
Sex and old age: As people move into their early 30s and 40s, sexual response greatly
decreases. Once you get to the 50s and 60s, sexual response goes back up again. This is
because adults have no energy to being too stressed out. However, once the kid moves
out they find time.
Hunger and Eating
Hunger is caused by stomach contractions called cannon. The hypothalamus regulates all urges like hunger and sex. It contains an “on and off”
switch for it.
Glucostats are neurons which measure how much sugar is in your blood, sending
messages through the vagus nerve that tell you if you are full or not and what kind of
food is being processed inside your stomach.
Insulin is a hormone in the pancreas that regulates the amount of glucose in the blood. It
makes you hungry. When the body doesn’t have enough sugar it starts eating up the body
organs in order to survive.
Ghrelin is an enzyme produced by stomach lining cells to stimulate hunger.
CK (cholecystokinin) is a hormone released by cells in the small intestine and its role is
to deliver feelings of being full.
Leptin is a hormone that is measured for information on how much fat is stored in your
Environmental Factors (On why you eat when you are bored)
Food Availability and related cues:
Commercials; Incentives (triggering hunger); Anticipated pleasure (seeing a cake that you
can only eat after dinner). Gerry, our teacher, did an experiment where he showed
cartoons to some kids with ads of chocolate chip cookies and some did not get to see any.
Then he gave them a tray of cookies. The more they saw – the more they wanted it.
