Coconut oil is an edible vegetable-based oil that can be used on external skin. While there is a lot of interest in using it as a lubricant during sex, there is no formal research on using it in this way.
Like all oil-based lubricants, coconut oil should not be used with condoms, as they damage latex and polyurethane condoms causing them to be more likely to break. If you are using condoms, it is safe to use water- or silicone-based lubricants.
If you do want to use coconut oil as a lubricant, be sure to do so with caution. People can be allergic to any type of substance so, be sure to watch for any changes in your genital skin, vulva and vagina/internal genitals, and stop using it if you notice any irritation.
Every vagina is different. Some people can use different lubricants and oils, and not have any problem with upsetting balance of the vaginal/internal genital flora; while for others, coconut oil may alter this balance, which can lead to yeast infections and/or bacterial vaginosis.
