How do I use condoms? Please take a look at the following steps:
First of all, needless to say, prepare a new condom. Then carefully open the package. Don't tear the condom inside. Otherwise, the consequences are very serious.
2. Hold the small bubble on the front end of the condom and wear it to the end of the condom. Special attention: The best time to wear a condom is after * * has an erection and before * * comes into contact with * * or the anus. "When using condoms, turning the foreskin up can increase flexibility and reduce the risk of condom breakage during sexual intercourse.".
3. While unfolding the condom to the root of the condom, continue to pinch the bubbles at the tip of the condom.
After * *, when * * is still in an erectile state, pinch the mouth of the condom and carefully pull * * out of the * *. "When removing a condom, do not allow semen to flow out, and do not allow the vaginal secretions outside the condom to come into contact with the body.". Each condom can only be used once, and used condoms should be placed in plastic bags and thrown into the trash can. It is not possible for the fingers that remove the condom to come into contact with semen and vaginal secretions at the same time. Therefore, after sexual activity, it is not allowed to touch female organs with your hands. You must immediately wash your hands with soapy water under flowing water.
Pay attention to the following items when using:
Choose a suitable size condom based on the size of your erection, usually in three sizes: large, medium, and small; Otherwise, if the condom is too large, it will easily slip off, and if it is too small, the quilt will become too tight and uncomfortable, affecting the body.
Do not place the condom in a personal pocket or near other heat sources, as prolonged exposure to heat sources can cause rubber aging. Do not use expired condoms, which are likely to rupture during pregnancy. Before use, the production date and expiration date should be checked. Expired condoms have deteriorated, are prone to rupture, and should not be used. Condoms must be stored in a cool, dry, and non contact environment with acids, alkalis, and oils. If it becomes sticky and brittle after contact with the above conditions, it should not be used again even within the shelf life. Condoms should only use water-based lubricants. Vaseline, liquid paraffin, facial oil, cooking oil, etc. can increase the fragility of condoms in a short time, accelerating their rupture.
Before use, blow the sleeve full of gas and pinch the opening to check for air leakage. When using, it is necessary to exhaust the gas, especially the gas in the sacs, to avoid rupture of the tip during pregnancy, which may lead to contraceptive failure. After pulling out, check the sleeve again for cracks. If it breaks, remedial measures should be taken.
If you find a condom slipping into the * * during * *, stop * * immediately, and gently insert * * with two cleaned fingers. Take it out. Do not continue using the condom. It is best to replace it with a condom before * *. If it slips into the * * after * *, actively take remedial measures, immediately instruct the woman to squat down, let semen flow out of the * *, wash the semen from the * * outer mouth, and inject contraceptive cream into the * *; To be cautious, it is best to take an oral contraceptive pill immediately, such as diethylstilbestrol 50 mg, for five consecutive days.
Following the steps above, it is believed that every boy can use condoms.
