Mastur–
Teen Shan: Charming the snake.
Flicking the bean.
Blowing your own horn.
Shan: Ok, enough with the euphemisms—
I’m gonna go ahead and just say it: Masturbation.
It’s something that many people
do throughout their lives.
And humans are far from the only
animals who like a little “me time.”
But sometimes masturbation is coupled with shame.
So let’s do what we do, and talk about it.
Hi! I'm Shan Boodram and
this is Crash Course Sex Ed.
[THEME MUSIC]
Masturbation is stimulating your
own genitals for sexual pleasure.
Which is a really clinical way to describe
something humans have been
enjoying for a long time!
According to evolutionary biologists and
some saucy prehistoric rock paintings,
humans have been masturbating for
probably as long as we’ve been around.
And if it’s not your thing, no sweat!
But if it is, you’re not alone,
even if nobody’s talking about it.
Surveys show that most people masturbate,
regardless of their gender, sexual
orientation, age, or relationship status.
Yeah, so it’s not just dudes and single people.
Masturbation is a totally
normal part of human sexuality,
and everyone has their own relationship
to it — including how they do it.
For instance, archaeologists have
discovered objects that were used
as sex toys going as far back as
the Han dynasty in ancient China.
And today, sexual aids are making it possible
for more people of all abilities to enjoy sex.
Teen Shan, let ‘em know.
In the 1960s, there was a
lot of “free love, baby.”
But not everyone was included in
this so-called sexual revolution—
especially disabled people.
They wanted to have sex—and did!—
but a lot of non-disabled folks
saw them as devoid of sexuality.
That’s where Gosnell Duncan came in.
In 1965, an accident left him
paralyzed from the waist down,
which caused him to not be
able to get an erection.
As he got involved in the
disability rights movement,
he learned he wasn’t the only one thinking about
the intersection of disability and sexuality.
Part of the problem? At the
time, sex toys were… not great.
Most were made of harsh-smelling rubber that
couldn’t be washed and that melted in heat.
So Duncan worked with a chemist to
create the world’s first silicone dildo—
washable, shareable, and easily
used with low hand mobility.
And even though he made it for disabled
folks, silicone became the thing in sex toys,
which makes for a nicer, more hygienic
time for people of all abilities.
The world of sex toys has come a long way
since those rubber dildos from the sixties.
Today, there are tons of different kinds for all
sorts of interests, sexualities, and abilities.
A few words to the wise when it comes to
sex toys: Use condoms for shared toys,
only use objects that are
specifically made for sexy time, and
— the golden rule —
nothing goes up the butt if
it doesn’t have a flared base.
Otherwise, it could get sucked up there.
Emergency rooms have truly seen it all, y’all.
So, masturbation is natural and
normal, and has been around forever.
But is paddling the pink canoe or
polishing the banister good for you?
Short answer: It can be!
Beyond just feeling good, many people have
reported that masturbation can help them relax,
relieve anxiety and pain, and fall asleep.
Scientists still have a lot
to learn about why that is,
but one reason could be the increase of the
hormones dopamine and oxytocin during orgasm,
which can counteract cortisol—AKA
“the stress hormone.”
Masturbation also stimulates the release of
neurotransmitters called endocannabinoids,
which regulate things like sleep,
pain, and immune responses.
And there might be some
long-term medical benefits, too.
Some research has even found
that for people with vulvas,
the increased blood flow from masturbating
regularly can help keep genital tissue healthy.
And other studies have found
that for folks with penises,
more frequent ejaculation has some
relationship with lowering the risk
of developing prostate cancer later on
in life, although it’s not clear why yet.
Sex educators have also observed that masturbation
can help people get to know their body,
and themselves as a sexual being.
It can help them figure out what
they like, what they don’t like,
and build a foundation they can
explore with others, if they choose to.
With women in particular,
studies have found that single
women who masturbated reported
being more sexually satisfied when they had partnered sex,
and overall, women who masturbate
are more sexually confident,
and have a more positive self-image.
And masturbation provides all of these
benefits with no risk of STIs or pregnancy.
Now that’s what I call an MVP.
Of course, there can be such a
thing as masturbating too much.
If it gets in the way of someone’s
responsibilities or social life,
it’s a good idea to talk
to a doctor or a counselor.
But in general, many studies have found evidence
that the five-finger shuffle can have upsides.
So… why do so many cultures give it a bad rap?
It turns out, people haven’t always
been cagey about masturbation.
Back in the timeline, people openly acknowledged
it more, including in creation stories.
Like, the ancient Sumerians believed one of
their gods created the Tigris and
Euphrates Rivers by ejaculating.
And the ancient Egyptians
believed that one of their
gods created the entire universe by masturbating.
Now that’s some BDE.
The ancient Greeks saw masturbation
as a normal bodily function,
but for them, it did have a judgey edge to it —
it was seen as something for lower-class citizens.
And they weren’t the last to
give masturbation some side-eye.
Many religions take a negative view of
self-pleasure, for different reasons.
Some see masturbation as an expression of lust,
while others teach that sex is something
a person should only do with their spouse.
But some of the shade has also come
from historical doctors and scientists,
whose inaccurate ideas have
bled over into the 21st century.
For instance, in the 1700s,
a famous Swiss doctor named Samuel Auguste Tissot
popularized the idea that semen was, quote,
a “vital fluid” that shouldn’t be
wasted on anything but procreation.
In what turned into a global campaign,
he and other doctors spread the belief that
masturbation made you weak and infertile.
And because back then, people thought
that semen originated in the brain,
they said masturbating would also
lose you a bunch of IQ points.
And the wrong ideas didn’t end there.
As time went on, people started to think that
masturbation wouldn’t just
cause physical problems,
but psychological ones, too.
In the 18th and 19th centuries,
medical practitioners said masturbation caused
disease, maladjustment, and even insanity.
Which led to some disturbing preventative methods.
Like, the Victorians used antimasturbation devices
that would hurt the penis if it became erect.
You could order one straight out of a catalog.
And self-proclaimed experts like
Dr. John Harvey Kellogg came up
with other gruesome ideas that are such
nightmare fuel, I’ll spare you the details.
His least horrible idea?
Probably that tasteless, fiber-rich foods
would keep the masses from masturbating,
which is part of why he invented…cornflakes.
No thanks.
Yeah, that Kellogg.
These days, there’s no evidence
that masturbating will hurt your
SAT scores or that it causes psychological issues.
But unfortunately, some new myths
have popped up in the last few years.
Movements like NoFap and No Nut November encourage
men in particular to abstain from masturbation —
because of the idea that not masturbating can lead
to benefits like increased testosterone long-term.
Which to be clear, has no scientific support.
The big takeaway?
Masturbation is a normal part of human sexuality,
and there’s no need to feel embarrassed about it.
No one’s gonna go blind or bald
or grow hair on their palms—
not from marching the penguin, or cuffing
the carrot, or turning on the sprinklers.
I could keep ’em coming too.
Next time, we’re wrapping up the series
by exploring what it means to be kinky.
I'll see you then.
