Human Sexuality
Talking about sex is taboo in some
cultures.
Sex education is a
new thing.
Your grandparents
probably learned
almost nothing
about sex in
school.
But it is important
to talk about it.
Talk to your parents about sex.
Talk to your partner about sex.
Be clear about
what you like
and don’t like.
When we are young, we are not
interested in the opposite sex.
This is because we don’t yet have testosterone
and estrogen.
But then puberty happens.
Hormones are released in your body.
And people start to feel sexual
attraction.
It’s a natural thing.
You don’t have to pretend you don’t want it.
Some people are heterosexual.
Some people are
homosexual.
About ten
percent of all
people are
homosexual. 700
million people in
the world!
Many animals are
homosexual too.
Are people born
gay? Maybe. But
it can change
throughout life.
Some people are bisexual.
Some people are transexual
Men and women are different.
• A man’s nature is to want to have sex often, and
with many different partners.
• A woman’s nature is to want one man who will
take care of her and her baby.
• These different wants and expectations can cause
problems in dating.
Some people repress their sexuality.
Catholic priests, nuns and
monks are not allowed to
have sex.
The average age of first sexual
intercourse in America is 17 years old.
And many people stay active
throughout their life.
Why do people try to look good, and
drive a nice car?
Because they want to find
a mate to make babies.
Why do we think some people are
“beautiful”?
Because they have
symmetrical features,
and are young and
healthy.
These kinds of people
are best able to make
healthy babies.
If people didn’t have sex, it would be
the end of humanity.
In some cultures, being a virgin is
important.
Some women
want to wait
until marriage
to have sex.
A virgin usually has a hymenเยื่อ หรหมจารี.
• A woman may
bleed during her
first time having
sex. Or she may
not.
• Sometimes a virgin
does not have a
hymen.
abstinence
Whether you have
sex or not is your
choice.
Just remember
that abstinence is
100 percent safe.
Masturbation สาเร็จความใคร่
• It is natural for everyone, and can relieve
stress.
• Too much masturbation is not good, especially
if you have an active sex life.
• In some religions, people cannot masturbate.
Sexual intercourse
The penis enters the
vagina.
It usually ends when
one or both people
have an orgasm.
There are many kinds of sex
• Normal sexual intercourse can make a woman
pregnant.
• A woman can not get pregnant from oral, manual
or anal sex.
• With normal sex, we should use a condom or
other contraception ยาคุม
How long does sex usually last?
On average, sex
intercourse lasts
from 5-7 minutes.
It usually doesn’t
last more than 12
minutes.
Orgasm จุดสุดยอด
• An orgasm is the most pleasurable moment in
sex.
• Orgasms are good for people’s health.
• A man’s orgasm lasts about 4 seconds. A
woman’s lasts 20 seconds.
• It takes longer for a woman to reach orgasm.
Is sex painful?
• Sex should not be painful, but it can be,
especially for women.
• If sex is painful, a woman should use
lubrication, or use a different position.
Why is it difficult to pee after sex?
• A man’s prostate is
closed during sex.
• It is good to pee
after sex, because
it cleans out the
urethra.
Can a man pee during sex?
• No. A man has a prostate gland which does
not let him pee when he is having sex.
Prostate
cancer is very
common in
men older
than 50.
Can a woman have sex while
pregnant?
It is normal and safe.
It is impossible to
make a new baby
when pregnant.
How many times can a person have
sex every day?
• As many as they want, but…
The body gets tired and needs to “recharge”
after having sex more than once or twice.
“Quality is better than quantity.”
The male reproductive system
erection
Nerves in the
brain send a
message, and
the penis fills
with blood.
An erection
should not
last for hours.
Penis size
• The average penis length is between 13 and
16 cm. Average thickness is 10 cm around.
• Longer is not always better! Women usually
like a thicker penis.
epididymal hypertension-“Blue balls”
• If a man has an erection for a long time,
without ejaculating, it can be very painful
because fluid builds up there.
ejaculation
During an orgasm,
the penis
ejaculates semen.
It comes out at
about 50 km per
hour.
Erectile dysfunction
Sometimes a man cannot get
an erection.
This can be caused by too
much alcohol, sex, age, or
mental issues.
Now men can use drugs like
viagra to help them.
semen
Semen becomes
hard when dry.
It carries millions
of sperm.
It’s thickness can
vary.
How long can sperm live?
• Sperm can live up to 5 days inside a woman’s
body.
The female reproductive system
The clitoris and the frenulum
These are the most sensitive parts of the body, and
give the most pleasure in sex. They should be
handled gently.
Frenulum
Clitoris
The penis and vagina are similar
What happens to the vagina during
sex?
• The vagina makes a kind of cream to help
lubricate.
• The inside and outside of the vagina get larger.
ovulation
The egg is coming out of the
ovary.
Sperm and Egg (ovum)
How does a woman know she is
pregnant?
• She will miss a period.
• Nausea
• Stronger sense of smell
• Fatigue
• Frequent urination
• Breast tenderness
Pregnancy test
Hold it in your urine
stream.
Two lines means you are
pregnant, one means you
are not.
Teen pregnancy
Do you know someone who has
gotten pregnant as a teenager?
In Thailand,
many women
become
pregnant as
teenagers.
Getting pregnant can destroy a young
girl’s dreams.
It may be difficult for a teen mother to
go to college.
The father may not want to take care
of the child.
The family may be angry or ashamed.
In some countries a
woman may be killed
if she becomes
pregnant before
marriage.
abortion
When a woman
doesn’t want to
have a baby, she
may have an
abortion.
This is not a good
way of birth
control.
It is illegal in
Thailand, except
when there is rape
or health
problems.
Fetus at 16 weeks
infertility
About 10 percent of
people have trouble
making a baby.
They can adopt a baby,
or use medical
technology to help.

have enough
sperm.
Sperm bank
