Can you use olive oil as lube?

Yes, with the same rules as coconut oil. Olive oil is slippery, long lasting and free of glycerin and fragrance. It destroys latex and polyisoprene condoms, it lingers inside because it is not water soluble, and it stains everything it touches. Use plain, food grade oil, keep a separate bottle, and stop if you notice irritation.

Why it works.

Olive oil is an oil, and oil does the one thing lube has to do: it reduces friction and keeps doing it. It does not evaporate or absorb the way a water based lube does, so one application lasts. It contains no water, so osmolality, the number behind most lube stinging, does not apply. It has no glycerin, no parabens, no fragrance, and it is already in the kitchen.

The three catches.

Condoms. The WHO/UNFPA/FHI360 advisory lists cooking oils among the products with a highly damaging effect on latex. Polyisoprene condoms fail the same way. Only polyurethane and nitrile condoms are oil safe. If condoms are in the picture, olive oil is out, no exceptions.

It lingers. Water based lube rinses out with the body's own fluids within hours. Oil does not. It coats the vaginal lining and stays, which for most people is harmless and for some, especially anyone prone to yeast infections or bacterial vaginosis, is enough to tip the balance. The 2013 study that linked petroleum jelly inside the vagina to bacterial vaginosis also found that women who used oils inside were more likely to carry yeast. There is no good trial on olive oil specifically. Try it, pay attention, and stop if something changes.

It stains. Olive oil on cotton is a permanent stain once it goes through a hot dryer. Keep a towel in the picture and wash in cold water first.

Two smaller points. It is not sterile, so keep a small dedicated bottle rather than walking the kitchen bottle back and forth. And plain only: nothing infused, flavored or garlic.

Olive oil versus coconut oil.

Both work, both break condoms, both linger. Coconut oil is solid in the jar and melts on skin, which makes it easier to handle and apply. Olive oil is liquid and runs, which means more on the sheets and less where it is wanted. Coconut oil is also closer to odorless; olive oil smells like olive oil. On the whole, coconut oil is the better of the two kitchen oils, and olive oil is the one you use because it is what is in the house.

When a real product is the better call.

If you like the oil feel and want something made for the job, Coconu Oil Based is a blend of food grade plant oils with no fragrance, packaged for the bedroom. Same condom warning, cleaner product.

If condoms are in use, or if yeast or bacterial vaginosis is a recurring problem, go water based. Good Clean Love Almost Naked measures 240 to 269 mOsm/kg with a pH of 4.7, inside the WHO ideal band of 380 or under, and it works with every condom and toy. It costs about what a bottle of decent olive oil does.

Nothing here is medical advice. Irritation that does not clear within a few days is a reason to see a clinician.
