What is sex?

Original Post

Adults have sex.

Sex is used by adults to create children. Adults have sex to create children, but adults love sex, so they also have sex even when they don't want to create children. This is because sex feels very good.

Sex is performed with a man's penis and a woman's vagina. Boys and girls only use a penis and a vagina to urinate. This is because boys and girls are still too young to use a penis and a vagina for sex. Once a boy or girl becomes an adult, their penis or vagina grows and becomes capable of having sex. Before an adult male has sex, his penis gets very big and hard. Before an adult female has sex, her vagina gets very wet. When adult men and women have sex, they get naked in bed and embrace each other. Then, the man takes his enlarged, erect penis and inserts into the wet vagina.

This is sex.

When a penis goes in and out of a vagina, they both feel very good. When the man's penis starts to feel so good he can't control himself anymore, a sticky white liquid called semen squirts out from the hole at the tip of his penis. When men squirt out a lot of semen into a woman's vagina, it feels very good and makes them happy. After the penis and vagina feel very good, and the penis squirts out its semen, sex ends.

Above is a picture of a man and woman having sex.

When adults create children, lots of semen squirts out from the penis into the vagina. When this happens, the semen sticks to the egg deep in the and changes it into a baby. When adults have sex but don't want to create a baby, they have to make sure the semen does not stick to the egg. To do this, they wrap the penis in a condom or take a special pill which prevents a vagina from getting pregnant even if a lot of semen squirts out of the penis. Adults work hard to make sure they can have sex without creating babies, because sex feels very good. This is how adults think of sex.

When you think about an adult man and an adult woman hugging each other naked and using their penis and vagina to do things like this, you may feel very embarrassed. However, having sex with someone you love feels very good, and this is why adults love having sex. Someday, you will become an adult, and you will want to insert your penis into the vagina of someone you love, or allow the penis of someone you love to enter your vagina. Then you will have sex, and you will want to feel the penis squirting out a lot of semen into the vagina. Someday, everyone should want to have sex with the person they love, use their penis or vagina to feel very good, and squirt lots of semen deep into the vagina in order to make a baby.

Men who are unable to ejaculate inside the vagina.

Original Post

During spring break, the sales of adult goods rises greatly in Japan. Perhaps it's because university and high school students take vacations during this time. In Japan, the spring break is longer than the summer break for university students, so I imagine there are a large number of couples in Japan who enjoy their vacation by bucking their hips and pleasuring each other on bed all day. I think there are a great deal of university student couples in Japan who are embracing each other's naked bodies, pushing their genitals hard together, and enjoying sexual climax together every day.

However, in Japan, I also hear about men who have problems ejaculating within the vagina during sexual intercourse. In Japan, it's called "internal ejaculation disorder," or "male vaginal numbness disorder." Despite being able to thrust their erect penises in and out of women's vaginas, these men cannot feel pleasure, and are unable to ejaculate inside.

Normally, if a man inserts his hard penis within a woman's vagina and thrusts it in and out, the friction will stimulate his penis and give him sexual pleasure. Even if he isn't moving, simply being connected with the female genitalia should stimulate him in some way. And, once he reaches the climax of his pleasure, he will ejaculate within the woman. This happens regardless of whether or not the man is wearing a condom.

When couples are trying to procreate, they work hard at having passionate, hard sex night after night, so that the man can repeatedly pump semen deep into the vagina. Not wearing a condom allows the penis to feel the full suction and stickiness of the vaginal walls, which should greatly stimulate the penis and allow it to powerfully ejaculate copious amounts of semen upon orgasm. In this regard, couples who are trying to procreate may be experiencing the most sexually pleasurable period any human being can ever experience.

deep ejaculation

Uniting the genitals and working hard achieve sexual stimulation is necessary for any couples to procreate. Without the ability to ejaculate inside a vagina, it will become difficult for a man to ever have children. Fertilization aside, not being able to ejaculate within a vagina may be a very sad thing to a man, and can impair his sexual enjoyment.

So, then, why do certain men have trouble ejaculating inside a vagina, when it is supposed to feel so good?

The problem seems to lie in how these men masturbate.

Apparently, roughly 15 years ago in Japan, there were no men who suffered from this sort of illness. At that time, it was normal for men to stroke their penises and masturbate while dreaming of sex, along with the aid of images and text. Imagining sex and masturbating was nowhere near as good as actual sex, so they were all able to enjoy sex because it always exceeded their highest expectations.

Now, however, adult videos are easily accessible, and in large quantities. The internet even allows us to see uncensored adult videos with the click of a button. These realistic records of sex are very stimulating to the eye, and can greatly influence virgins who watch these videos constantly and masturbate to them. There are also many different types of adult videos now. Some videos are shot from the male's point of view, allowing the viewer to imagine themselves in certain situations. The actions, the bouncing of the breasts, and the cries of the women are all so real that it allows some men to imagine that they're actually the ones having sex instead. Uncensored adult videos also allow men to see women's vaginas and clitoris, watch powerful, erect penises thrust roughly in and out of wet vaginas, and even see throbbing penis ejaculating sperm up close. To a virgin, who has never seen a real woman's vagina, and never experienced real sex, watching these sorts of videos over and over again and masturbating to them may confuse their brains into thinking that this action is real sex.

Adult videos allow people to experience sex in video and audio, but it's missing some key components. The feeling of embracing a naked woman and the feeling of penetrating a woman with one's penis cannot be experienced through adult videos. And real sex is not merely using a woman's vagina to masturbate one's penis. All that exists during masturbation is visual and audial information and a hand stroking a penis. Training the brain to make the penis ejaculate upon receiving this sort of information may make a penis unable to ejaculate when experiencing the soft sensations of an actual vagina.

real sex

Therefore, I recommend masturbating while reading sexual experience stories or other fictional stories composed of text. (Personally, I enjoy doing this.) I also think there is a problem with stroking a hand harder than the pressure one usually feels when penetrating a vagina. During masturbation, you should not grind your penis against something, but rather, stroke it with moderate strength.

Of course, in order to maximize one's potential of sexual stimulation during real sex, the best thing to do may be to not masturbate at all. But every man wants to masturbate at least a little to feel the pleasure of ejaculation. However, I will repeat, I highly recommend that virgins use only text, not adult videos, in order to masturbate, in order to maximize the pleasure when you finally have sex with a woman you love.

About the Vagina, Part 2.

Original Post

Today we will talk about the inner female genitalia.

The inner workings of the vagina are illustrated below.

The vagina is where the male inserts his penis during sexual intercourse. It is made out of soft, elastic membranes that can gently take in any penis, no matter how large. There are many folds on the walls of the vagina, and women in their teens and twenties usually have about 60 folds that are each 1 to 2 millimeters high. During sex, these many folds wrap around the male's erect penis and stimulate the penis as it moves in and out of the vagina. Incidentally, in Japan, there exists the term "meiki," or "exquisite organ," which refers to a vagina that feels exceptionally good upon penetration. These exquisite organs usually have around 100 folds that are each 3 to 4 millimeters high.

During sex, the woman's vagina takes in the man's penis, and the man thrusts his penis in and out in order to receive stimulation. When the penis receives a certain amount of pleasure, it reaches orgasm, upon which a large amount of semen is ejaculated out from the penis deep into the vagina.

After semen fertilizes the egg in the woman's womb, it becomes a place for a baby to grow in until birth. The ovaries, the follicles that produce eggs, are prepared with around one to two million eggs, and deposit them in a cycle of about 28 days. Ovulation is when the eggs move along the fallopian tubes to the womb. If a man and woman engage in sexual intercourse after an egg has been delivered to the womb, it becomes possible for semen to fertilize the egg.

About the Vagina, Part 1.

Original Post

Heterosexual intercourse is an act of reproduction performed with the male and female genitals. If you plan on having sexual intercourse in this manner, you would do well to learn all you can about the male and female genitalia.

Today we'll be talking about the outer parts of the female genitalia.

Those who often enjoy sex with girls should be using to seeing what is pictured above.

Many people say that the female genitalia are pink, but the actual color depends on the amount of melatonin pigments present within them. Therefore, depending on the person, some female genitalia may appear darker in color. The color does not necessarily darken based on how many times sexual intercourse is performed.

The clitoris is a very sensitive part of the female genitalia, and stimulating should provide the female with intense pleasure. It is the equivalent of the male penis, and since there are so many pleasure sensors concentrated within it, it is actually capable of achieving a greater level of pleasure than the male penis. Like the male penis, when aroused, the clitoris becomes erect. When having sex, try stimulating it with the hand or pelvic bone.

Just below the clitoris is the urethra, the hole that urine comes out of. When women squirt, the transparent secretions squirt out from this hole.

Below that is the vaginal opening, the orifice that the male sticks his penis in during sexual intercourse. Any heterosexual male who has passed puberty will most likely, at some point or another, think about inserting his erect penis into the vaginal opening of the girl he likes and ejaculating within. It is composed of very soft membranes, and opens to allow erect penises inside. If semen is ejaculated deep within, the woman can become pregnant. When the baby is born from this hole, it expands to a very large size.

On the left and right of the vaginal orifice are Bartholin's glands, vessels that deposit secretions when they receive sexual pleasure. This is what allows the male to thrust and pull back his penis smoothly. I recommend making sure this orifice is very wet before slowing inserting an erect penis inside.

Next time, we'll discuss the inner parts of the female genitalia.

Erection and ejaculation.

Original Post

Many couples are enjoying good sexual intercourse right as I type this. Sex is a way for men and women to communicate using their penises and vaginas. The penis is a genital designed to enter a vagina, and a vagina is a genital designed to receive a penis. By connecting their genitals, men and women can deepen their relationships, and ejaculating semen deep inside a woman's vagina can impregnate her. Incidentally, this act can feel very good and bring happiness to both parties.

thrusting animation

Men have penises, and when they feel erotic, their penises become erect. This makes them want to insert their penises into a woman's vagina. Becoming erect in this way allows them to more easily penetrate the woman's vagina. In the above animation, the man is enjoying inserting his penis over and over again into the woman's vagina. This act feels extremely good to both the man and the woman when sex is done properly. When a man inserts his penis into a woman's vagina enough times, it reaches the climax of its pleasure and ejaculates. Ejaculation feels extremely good to men. Ejaculating semen deep into a woman's vagina will impregnate her.

But how exactly does a penis become erect and ejaculate?

When couples feel erotic with each other, they have sex. They kiss, touch each others' bodies, and sexually stimulate each other so that sex may begin. When men become sexually excited, their brains send signals to their genitals. Their blood pressure also increases, they sweat, and become duller toward pain. They also become concentrated on having sex.

The penis is formed out of sponge-like tissue called erectile tissue, which arteries flow through. When men become sexually aroused, their brains order nitric monoxide to become produced. The nitric monoxide loosens the smooth muscles in the arteries of the penis and increases the amount of blood inside it. In the end, these enlargened blood vessels fill the space in the erectile tissue, which makes the penis become hard. This is what an erection is.

Sex does not feel good unless a penis is erect, and it's hard to enter a woman's vagina if it's soft. Being erect allows a penis to powerfully thrust into and stir around inside a woman's vagina, stimulating it with the friction of the vagina's taut walls.

There are many ways for a penis to move inside a vagina, such as piston movements and revolving movements. Merging genitals like this and rubbing them together is how couples have sex. Most couples love this feeling and rub their hips together to gain as much pleasure as they can.

The more a penis thrusts inside a vagina, the better it feels. The nerves in the penis concentrate at the tip, and it feels very good when it rubs up against a woman's vagina. When its pleasure reaches a climax, the man's brain sends signals to the testes, which begin preparing for ejaculation. Sperm that has been alive for around 70 days n the testes are then sent to the ampulla of the vas deferens. Then, as the penis continues thrusting inside the vagina, the sperm mixes with liquid secreted from seminal vesicles in the prostate and becomes semen, which is ejaculated through the urethra.

When the man's excitement increases, his brain is satiated with pleasure. Then, the man reaches orgasm, and the muscles around his prostate and penis begin to spasm. This pressure ejaculates semen out from the urethra at the tip of the penis. This is ejaculation. In a steady rhythm, semen squirts out from the penis over and over again and flows deep into the woman's vagina.

Men ejaculate by flexing their prostate. Flexing these muscles feels very good to a man. Each time the penis pumps and ejaculates more semen, the man is filled with pleasure. Some women may be able to feel the erect penis throbbing within her as it pumps the semen out. If sex is being done properly, this pumping should fill both the man and woman with a heavenly level of pleasure.

After powerfully ejaculating within a woman's vagina, the penis gradually stops spasming, and ejaculation ends. After this, the man slowly cams down and pulls his penis out from the vagina.

This bodily process is what allows sex to feel so good. Whenever I ejaculate, it always feels so good that I unconsciously hug my girlfriend's body toward me. And when I do this, she feels my penis spasming inside her, squeals in joy, and hugs me back. I hope that many more couples can also ejaculate in a similar way, so that the female can enjoy the ejaculation along with the male.
