Yes, you can use coconut oil as a lube! Not only that, but it is my favourite choice, as long as you are not dependent on condoms for birth control, because any oil can degrade latex. If you use condoms choose one of the non oil based lubricants. Coconut oil has natural anti-fungal & anti-bacteria properties, so if you are susceptible to yeast infections or vaginosis, this is a great choice for you. Coconut oil is a great lube because it is 100% edible, so makes a great choice for oral sex. Another perk of using coconut oil as a lube is it won't stain the sheets.
