Many young men and women want to get the satisfaction of not wearing a condom by "rubbing".
But this "borderline sex" also has the potential to make girls pregnant.
If you accidentally come to an "unplanned" baby, it will be embarrassing.
Today, we will talk about those "unreliable contraceptive methods" circulating, don't believe it again!
The truth
The so-called "rubbing" also has the probability of "wiping the gun and going off the fire" and "hitting it with one hit".
This is because, during the snapping process, boys will secrete prostate fluid and seminal vesicle fluid due to excitement, which also has a small amount of sperm.
Once the little tadpole and the egg baby successfully "meet the teacher", the next "lucky pregnant child" is you!
As for what some people think, as long as the hymen is still intact, sperm will not enter the vagina, this idea is also wrong.
It should be known that the hymen is a membrane-like structure with holes, and this membrane can neither prevent menstrual blood from draining, nor can it prevent small tadpoles from entering.

So, stop believing the "rub and don't go in" bullshit!
1. Extracorporeal spermatogenesis contraception?
Don't believe it!
The contraceptive failure rate of this method is extremely high [1].
Because men are in the moment of excitement, it is not easy to control the time and rhythm of the outset, and there are inevitably some small tadpoles overflowing, which cannot be controlled artificially.
2. Don't wear a condom during the safety period?
The rate of contraceptive failure during the safe period is 25.1% [2].
The "first seven and then eight" principle of girls calculating the safe period is only a rough estimate of the ovulation period, and many external conditions can affect the time of ovulation.
For example, long-term mental stress, excessive weight loss, frequent staying up late and other factors may affect the secretion of estrogen and progesterone, which in turn can cause delayed ovulation in the ovaries.
For most girls, safe period contraception is not reliable.
3. Can vaginal irrigation immediately after sex prevent contraception?
For small tadpoles that have already entered the uterine cavity, vaginal irrigation has no effect and may damage the vaginal environment and induce the risk of bacterial infection.
There are only two ends to being pregnant before marriage, either bleeding and shedding tears, or "liking to be a father".
Little fairies who have no intention of procreation must remember:
No matter what kind of abortion, it is a human termination of normal pregnancy, which may damage health!
For example, the drug flow may cause bacterial infections (such as endometritis), anemia, decreased immunity, etc., and may also cause amenorrhea, premature ovarian failure, etc.
Abortion surgery may cause uterine perforation, heavy bleeding, postoperative uterine cavity infection, adhesions, etc. Repeated abortions may also increase the probability of infertility [3].
Friendly Reminder:
Some advertising "easy three minutes, painless abortion without a trace", the so-called "painless", is really limited to the time of intraoperative anesthesia.
The "pain" after the operation is guaranteed to be something you will never want to experience.
The principle of contraception mainly interferes with 4 key links in the conception process:
Ovulation of the ovaries;
Sperm enter the uterus;
Egg cells bind to sperm;
Fertilized egg implantation.
Contraception is different for different populations and situations.
1. Wear a condom throughout
With proper condom use, contraceptive success rates are over 97 percent [4], safe without side effects, and sexually transmitted diseases can be avoided.
2. Short-acting contraceptives
Needs to be taken on a cycle (5 days after the end of the last menstrual period, start taking continuously).
Take a cycle of 28 days, after 21 days of continuous use, discontinue for 7 days (usually, withdrawal bleeding will occur within these 7 days, which is equivalent to a menstrual period).

After that, regardless of whether you have a menstrual period or not, you should start taking the next cycle of contraceptives on the 8th day of stopping the drug [5].
Note: Only under the premise of regular use, there is a better contraceptive effect. If it is missed, the contraceptive effect is greatly reduced.
In addition, people with long-term smoking habits and obesity are not recommended to take short-acting contraceptives.
As for long-acting and emergency contraceptives, they are generally not recommended for routine contraception.
3. Subcutaneous implant contraception
Make a small 2 mm opening in the arm and put in a silicon capsule the size of a grain of rice to slowly release the contraceptive drug in the blood, thereby maintaining a low and contraceptive concentration, which can achieve a contraceptive effect of 5 years.
This method is efficient, long-term, convenient and reversible. Subcutaneous implantation of contraception for three years, the cumulative rate of unintended pregnancies is less than 0.05%[6].
However, there are some contraindications and side effects, such as 6 weeks after childbirth, coagulation dysfunction, epilepsy, hepatitis, cirrhosis, etc., which are not suitable for this method [7].
The cost of subcutaneous implant contraception is 1000 to 2000 yuan, which is suitable for healthy women of childbearing age who are economically allowed and have no contraindications. (It is recommended to go to the obstetrics and gynecology department of a regular large hospital for consultation)
4. Ligation
One step in place, both men and women.
But the key question is: Who does it?
"There are tens of millions of roads, safety is the first, driving is not standardized, and relatives are in tears."
In order to ensure the safety of "bed driving", please remember the 5 points of precautions for "wearing seat belts":
1． See the expiration date of the condom! Once expired, latex may age, lose its elasticity and crack easily.
2． Do not apply oily lubricant to the sleeve yourself, as it will break down the latex, causing many tiny holes and increasing the probability of contraceptive failure.
How do you tell if it's oily or not?
In fact, there are very few oil-based lubricants sold on the market, and most of them are replaced by water-based and silicone oil lubricants.
When purchasing lubricants, you should carefully look at the ingredient list, if there is glycerin, silicone oil, etc., you can use it with confidence.
3． Before use, remember to pinch the seminal vesicle at the front of the sleeve to drain the air so that the small tadpoles do not slip out from both sides of the sleeve.
4． Remember to keep condoms in a cool, dry place.
5． Choose regular manufacturer products, choose the appropriate size, and standardize the use of condoms. Note that there is no need to save the environment here and do not recycle.
Although many boys do not like to wear condoms, Zhimei still has to say:
Whether it is love or sex, we must respect each other's wishes, understand each other, and protect each other.
I hope that every boy will stop rejecting condoms, because protecting the health of both parties and trusting each other is definitely more important than sex.
I also hope that every girl can stick to her principles, you know, a compromise can cause permanent physical and mental harm!
Remember to collect this article, if the boyfriend fools you again that you don't wear a condom, immediately dump it at him!
