Japanese Sex Essentials

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.

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.
