Most of the oil on the condom will be discharged with the secretion after sexual intercourse, but a small amount of oil will remain in the body, basically it will be gradually discharged with the secretion in about 24 hours. You can wash your vagina with lukewarm water after sex to minimize the amount of condom oil left in the vagina. The main ingredient of condom oil is dimethicone, which is a common lubricant that can play a lubricating role and reduce the damage to the female vagina. However, some women are allergic to this ingredient and may experience discomfort such as vaginal itching and redness. Therefore, when shopping for condoms, you should check the instructions carefully. If you are allergic to any of the ingredients, you can choose other methods of contraception, such as taking the pill. A small number of condoms use methyl silicone oil, which is a weakly alkaline ingredient and is not volatile or easy to clean, and its long-term use may damage the acidic environment in the female vagina and even cause gynecological inflammation. Therefore, it is recommended to avoid choosing this type of condom as much as possible, but also to use warm water to clean the pubic area in a timely manner after unavoidable use. When choosing condoms, we should buy condoms produced by regular manufacturers through regular channels, avoid buying three products, otherwise not only the quality can not be guaranteed, but also may have a negative impact on health. At the same time to look at the shelf life, the use of expired condoms may not be able to play the role of contraception, and due to the expiration of the lubricant, may also lead to both sides in the sex life of the injury. Do not apply cooking oil, baby oil, etc. instead of condoms on your own, it is unsafe and unhygienic.
