Eight possibilities of condom contraceptive failure

3. Accidental rupture during sexual intercourse, such as excessive range of sexual intercourse, fingernails or rings inadvertently scratching lead to ultra-thin condom damage.

8. Improper storage, such as condom exposure to bright light, high heat, humidity and ozone will lose its intensity.
How to achieve the effect of contraception?
1. Every time you have sex, you must use a new colloidal condom; you must wear it before intercourse and after an erection; carefully tear open independently sealed bags to avoid using sharp tools such as scissors; squeeze the front end of the condom with your fingers and squeeze the air out of the erectile penis; keep the space at the front end of the condom
2. Make sure the condom covers the entire penis; if necessary, choose a water lubricant. Oily lubricants (such as glycerin and Vaseline) can cause condoms to break.
3. After ejaculation, hold the edge of the condom tightly and pull it out while the penis is still erectile. Do not keep the condom in the wallet or near the heat source for a long time.
