Japanese Sex Essentials

Original Post

During sex, the man makes his penis erect, inserts it into the woman's vagina, adn bucks his hips in order to stimulate both genitals and increase their excitement. When the penis reaches the climax of its pleasure, it ejaculates semen deep into the vagina. Being erect during ejaculation allows the penis to better deliver semen into the uterus.



Perhaps this is a simple fact that even most elementary school students understand. However, it is possible for a penis to enter the vagina while soft, as long as the vagina is moist enough, which means it's also technically possible to have sex without a penis being erect.

A man being flaccid during sexual intercourse is a sad thing. When flaccid, no matter how hard the man bucks his hips, it will be hard for the woman to feel stimulation. The man will also not be able to feel very much friction on his own penis. Thrusting forward and and giving the woman pleasure will not be possible in this state. Forcefully stretching the penis skin like this can cause phimosis. (The same can be said for masturbation.)

An erect penis, however, can slide powerfully against the walls of the vagina and create strong pleasure.

And ejaculation. If flaccid, an ejaculating penis will not be able to give much pleasure to a vagina. A fully erect, aroused penis, however, will powerfully squirt out semen into the womb, and the throbbing as this happens will stimulate and arouse the vaginal walls. This sort of pleasure will be greatly lessened if the penis is flaccid.



Therefore, for best results when having sex, I greatly encourage the man to make his penis fully erect, insert it deep into the woman's vagina, and allow it to powerfully ejaculate. If a penis is allowed to enter the vagina while flaccid too many times, it will become harder and harder to make it erect. Even when masturbating, be careful that your penis is fully erect and hard before ejaculating.
