Japanese Sex Essentials

Original Post

Is there anything more pleasurable to a man than ejaculation? When a man has sex, his penis grows erect. Then, he slowly inserts his erect penis into women's vagina and has sexual intercourse. By bucking his hips back and forth and moving his penis in and out of his partner's vaginas, it makes his penis feel better and better. When his pleasure reaches a climax, the man ejaculates, delivering lots of sperm into the woman's vagina. Sending semen into a woman's vagina like this feels extremely good to men, and it brings them a special joy to know that they may be impregnating their partner with their own semen. It's a good thing procreation comes with such pleasure, wouldn't you agree?



Sperm is produced in the testicles, and matured in the epididymis. When a man becomes aroused, the sperm in his epididymis is sent along with secretions to the ampulla of the vas deferens. Then the man starts to feel even better.

When a man's pleasure reaches it climax, the sperm in the ampulla travels through the ejaculatory duct until it is supplied out from the prostatic portion of the urethra. This is where it mixes with prostatic fluid.

During this process, the prostatic portion of the urethra is compressed by the urethral sphincter's contractions, pressurizing the sperm. After this, the urethral sphincter relaxes, and this pressurized sperm is pushed out from the urethra with great force along with seminal vesicle fluid.
