- High failure rate, low efficiency is only about 60-70%. In the process of implementation requires strict adherence to the actions during intercourse. Particularly, the strong determination of men is a prerequisite for the success of the method

 

- This method is very easy to cause mental pressure for men, making them always stressed to calibrate when the penis is withdrawn. The withdrawal greatly reduces the pleasure of men when it is near the peak and at the same time it is easy to cause depression in women. Over time, it can make you both lose interest in sex.

 

- This measure, if used regularly, can cause men to be impotent or have premature ejaculation.

 

In addition, to keep the ejaculation inside, many men have to use their hands to compress the urethra (compression of the pelvis in the posterior urethra - the area between the anus and the outside genitalia).

 

- Some men use their hands to compress the urethra to prevent semen from discharging into the vagina but cause semen to flow back into the bladder, accidentally leading to the risk of urethritis, upstream ejaculation.

 

- This measure cannot prevent sexually transmitted diseases such as syphilis, gonorrhea, fungus, HIV, etc.

 

When ejaculation outside often, the time when the woman reaches orgasm will feel depressed, sometimes it will cause a woman's apathy. Most cases of vaginal ejaculation, the woman feels depressed, so should only be applied in cases of force majeure.

 

Easily nervous breakdown During the process of "love", sexual inspiration in men is controlled by the cerebral cortex. When you reach orgasm, your nerves go into a state of stress, tachycardia, and high blood pressure. If during the sudden climatic interruption, it will create a bad influence on the psychology of sex, gradually causing the nervous direction of sex to decline, leading to premature ejaculation or impotence. Husband and wife's disagreement Sexual harmony is an important condition to help them build up their feelings. But regular ejaculation outside will make the couple have a distance, difficult to get along with each other. In addition, if this method is applied, the wife is still pregnant will make the man suspicious, thereby leading to discord in the family. Moreover, using this method makes it difficult for the wife to satisfy, causing psychological pressure leading to cheating the couple. The risk of sexually transmitted infection If the contraceptive effect by making the "little boy crying outside the border" reaches about 70%, the effectiveness of avoiding sexually transmitted diseases is almost zero. Because, bacteria completely can penetrate the partner's body through direct rubbing, especially in mucus that also contains a large number of bacteria. Therefore, to prevent sexually transmitted diseases such as syphilis, gonorrhea, fungi, HIV ... it is best not to use the method of vaginal ejaculation. When both sex is close to the climax and suddenly stopped, the feeling of satisfaction will not reach the maximum level. When "in love", the man in a state of excitement and "climax" is the climax. Before ejaculation, but "rushing to gun" is like rushing to withdraw, will cause the central nervous system to stimulate and disrupt the ejaculation control agency. This condition lasts long leading to the disease of semen - semen comes out naturally without pleasure or stimulation. Ineffective in contraception In addition to the advantage of being simple, easy to carry out, consistent with the "lazy" disease using condoms, oral contraceptives ..., almost vaginal discharge does not bring good results. In case of ejaculation outside but semen is flowing into the vagina, the partner is easy to "stick" to vote.
