Japanese Sex Essentials

Original Post

The ultimate purpose for sex is to bear children. Men ejaculate so that their sperm can be delivered to women's wombs, fertilize their eggs, and create a new human to carry on their DNA.

It starts with an erection.

When men are sexually aroused, their brains order their bodies to collect nitric oxide. The nitric oxide that collects in the smooth muscle known as the penis slackens it and then increases blood flow in the erectile tissue. The swelled-up blood vessels fill the gaps in the erectile tissue and harden the penis due to blood pressure, making it erect. The more slack a penis starts out, the more blood can flow in and make it even harder. Treatment to counteract impotence focuses on this very act of collecting nitric oxide in the penis, making it easier for penises to become erect without any sexual arousal.



Deliver semen into the womb.

When his penis becomes erect, a man inserts his penis into a woman and has sex. By bucking his hips, he increases his sexual arousal by the friction and eventually ejaculates. He continues bucking right up until the point when he ejaculates, when he stops instantly, sticks his penis as deep as he can into the woman's vagina, and then delivers his sperm. Personally, it's hard for me to keep bucking my hips as I ejaculate. It probably has something to do with my instinct that tells me it's easier to impregnate a woman if my penis goes deeper into her vagina. Doggy style allows men to insert their penises very deep, so it's a good position for this.



Conditions that encourage impregnation.

It's easiest for women to get pregnant right before they ovulate. Sperm can survive after they're ejaculated in vaginas for three to four days, some even for a maximum of ten days. Eggs only last for one day after they're ovulated. A degree of good timing during these conditions for pregnancy to happen. Ovulation days can be calculated by the basal body temperature method and by inspecting saliva.

Also, men's sperm counts are refilled completely two or three days after their last ejaculation, so it's best to wait until your sperm count is refilled if you want to impregnate your partner. Ingesting lots of zinc will increase your sperm count and make them more energetic, so I would suggest zinc supplements to men who wish to ejaculate lots of sperm.



However, waiting too long to ejaculate may not necessarily be a good thing. 2 to 5 days maximum is best to increase the quantity and thickness of sperm. If a man waits too long between ejaculations, the sperm production in his testicles may stop, and the produced sperm may age, losing energy. No more than one week is recommended. It's also important to make sure your semen does not leak out of the vagina after ejaculation. Try staying still and keep your penis inserted for twenty to thirty minutes after ejaculation. Finally, sex between October and May, having sex in a bright place, and having good, satisfying sex can also encourage pregnancy.
