Japanese Sex Essentials

Original Post

In Japan, spring is known as a season of new meetings. This season is thought to contain chances of people to meet new partners of the opposite sex, so I encourage people in Japan to proactively seek new partners during this season. I imagine there are a great number of couples who meet in spring, start dating each other, and then begin engaging in sexual intercourse long before summer begins. For people who have never had sex before, this gives them a lot of time to enjoy sexual pleasure in a variety of positions and get used to sex before summer begins.

Today, we'll be talking about internal ejaculation, which is known in Japanese as "nakadashi." I imagine there are a great many men who fantasize about ejaculating directly inside a vagina.



Internal ejaculation is when the man inserts his erect penis into the woman's vagina without using a condom, and directly ejaculates semen deep inside it. Originally, internal ejaculation was done in order to impregnate women. The sperm within the semen that is ejaculated mixes with the egg deposited into the woman's womb by the ovaries and creates a baby.

Internal ejaculation itself feels very good. First of all, it allows the man to feel the inside of his woman with nothing but his bare penis. The vaginal membranes stimulate the penis and entice it to piston harder in order to receive more pleasure. Then, the penis continues its thrusts without stopping until it climaxes and ejaculates semen deep within the vagina. Pumping out semen into the vagina of a girl you love and filling it up is a very pleasurable act for a man. Impregnating that same girl with the semen can also fill a man with a great sense of satisfaction.



Likewise, internal ejaculation allows the woman to feel the penis of the boy she loves spasming and pumping lots of semen deep inside her, which should fill her with a deep sense of satisfaction. If she truly loves the man, then feeling him impregnate her should fill her with a powerful joy.

Internal ejaculation sex is something that many couples have done in order to create children. It feels very good, which is what brings so many humans to create grandchildren.

There are also many couples who take part in internal ejaculation sex even when they don't want to create children. They do it purely because they seek the intense pleasure that comes from it, and the truth is, even middle schoolers and high schoolers in Japan are internally ejaculating within one another, and quite often, in fact. This is because recently, various different types of contraceptives have been created which are far more effective than condoms.

Here are the six major contraceptives that exist:
1. Condoms
2. Diaphragms
3. IUDs
4. Mirenas
5. Pills
6. Spermicides

Diaphragms, IUDs, and Mirenas are all contraceptive devices that are installed inside the vagina. Contraceptive pills as well as morning after pills also exist. It seems that recently, couples who want to enjoy internal ejaculation often use contraceptive pills. The reason we see so much international ejaculation in adult videos recently is probably due to the mass proliferation of these pills. It's been a long time since they were introduced in Japan, are available publicly, and allow couples to enjoy internal ejaculation lifestyles where semen can be constantly ejaculated into the vagina every day without any risk of pregnancy. Even high school girls can start using pills, which means it may become a general contraceptive method in Japan in the future. Additionally, the basal body temperature method is apparently not very effective when it comes to preventing pregnancy.



When I have internal ejaculation sex with my girlfriend, I apply a spermicide within her vagina five minutes before sex. Depending on the position, the spermicide may drip out of her vagina, but apparently this doesn't have much effect on the actual contraceptive method itself. If used properly, it really does prevent pregnancy.

As you can see, there are many different contraceptive methods available now, which makes internal ejaculation much more possible than before. I imagine that from here on out, couples that regularly engage in internal ejaculation will increase and enjoy pleasurable, satisfying sex for their entire lives.

Yesterday I went to the pharmacy to buy condoms. I planned to use them when having sex with my girlfriend, of course.

Lately I've been using Okamoto 003 condoms. But then, I noticed that a new product in the 003 series had hit the market.

003 RF. The "Real Fit" condom.

The 003 RF is a completely different shape than the 003. The 003 had a reservoir tip and looked like a regular condom, but the 003 RF is shaped exactly like a penis. it doesn't even have a reservoir tip.



Since it perfectly fits my penis, it never slips off, no matter how roughly I thrust inside my girlfriend. It also feels a lot more like having sex without a condom. It never slips, and there's no reservoir tip, so it feels a lot more natural. And since the end is shaped more like an actual penis head, it feels better for the woman.

My girlfriend even said "the old condoms made it look like you were sticking a fish sausage inside me." With these new condoms, it feels more like having sex with a naked penis to her.

At the pharmacy near my house, it cost 700 yen for 5 of these condoms. That night, I was able to have very good sex. From now on, I think I'm going to keep using these condoms. The fitting sensation was out of this world.

It's almost Christmas, so how about giving the RF condom a try yourself?

Hello. Summer vacation has begun. But it looks like this is the last summer I'll have to play around.

Yesterday, I got into a fight with my girlfriend. It was just a little fight, but thanks to it we got to make up and have romantic sex.



Make-up sex is always more romantic than normal. Our kissing is harder and feels better than usual. This time, I ejaculated inside her. It really felt good. I always ejaculate faster when I insert my penis into her without a condom on.

Apparently women can feel it when men ejaculate inside them, especially if it's around the entrance to their vaginas.

I recommend using contraceptives when ejaculating inside your partner, especially Poon Neosan Loop tablets. All you need to do is slip it inside your partner's vagina five minutes before you have sex. The tablet will dissolve in five minutes, and then you can insert your penis. It may feel like she is a bit warmer than usual, but it still feels great. My partner also likes it when I don't use a condom. I always ejaculate deep inside her. The chemicals in the dissolved tablet kill my sperm, and it's very effective if used properly. I recommend using it together with some other type of contraceptive.

Yesterday, I had sex with my partner in her room. At the time, there were condoms on sale for cheap at the local drugstore, so I picked up a pack.

They were polyurethane condoms.



Polyurethane condoms feel better than rubber condoms.

Compared to rubber condoms, polyurethane condoms get stuck less and don't stretch due to vaginal friction. Because of this, the feeling of the inside of the vagina is transmitted more directly to the penis, and so it feels like you aren't wearing any sort of condom at all. They also have high thermal conductivity, so you can better feel the warmth of your partner.

Thin but safe.

I usually find the "Sagami Original 002" brand condoms at my local drugstore. They're only 0.02mm thick, unlike any rubber alternative. Since they're so thin, it really feels like you aren't wearing any sort of protection at all. Also, even though they're so thin, polyurethane is actually safer than rubber. Rubbers can sometimes break when you insert your penis into a vagina, but polyurethane is stronger and doesn't break so easily.

You can have sex without worrying about the condom.

It's difficult for polyurethane condoms to just slip off, so you can buck your hips all you want and enjoy sex without worrying a bit about the condom itself. They're often more expensive than rubber condoms, but if you have some change to spare, I definitely suggest you pick up a pack of polyurethane condoms.

Have any of you ever had sex during a woman's period? I have sex with my partner even when she's on hers.


Being on her period only lowers the woman's chances of getting pregnant.

I've heard many stories about people ejaculating inside their partners while they're on their periods thinking that it would keep them from getting pregnant. I've also done it myself. (And it did feel good...) But the question is, can a woman actually get pregnant while she's on her period?

The answer is yes. It's possible to impregnate a woman while she's on her period. Ejaculated semen can live from four to ten days inside a woman's vagina and womb, and it's possible that a new egg could be impregnated during that term. Also, with women whose periods don't always come at the same times, it's impossible to accurately predict when she will or won't ovulate.

Sex encourages ovulation.

When mammals have sex, the stimulation causes more hormones to be secreted within their bodies, encouraging ovulation. Humans are also mammals, so it's possible that sex could encourage ovulation within us as well. This means that period or not, having sex always means there's a chance the woman could get pregnant.

Period sex is unsanitary.

When a woman goes on her period, her endometrium gets torn off and her cervix opens wider than usual. In other words, it's practically defenseless against viruses and bacteria. This is another good reason to avoid sex while a woman's on her period.

If you still want to have sex with your partner while she's on her period, then I suggest using another contraceptive method. But thinking of how unsanitary it is, I really feel it's best to avoid it altogether.
