You're in the middle of things and realize the drawer is empty. It happens. Usually, the first instinct is to lunge for whatever is on the nightstand or in the bathroom cabinet. Lotion? Coconut oil? Maybe that fancy organic olive oil from the kitchen? Stop. Before you grab the nearest bottle of liquid, you need to know that your body—specifically your mucous membranes—is incredibly picky about chemistry.
Figuring out what to use as lube isn't just about reducing friction; it’s about pH balance, osmolality, and not ending up in an urgent care clinic with a yeast infection that feels like a chemical burn.
Most people think "slippery" equals "safe." It doesn't.
The reality is that your internal tissue is a delicate ecosystem. When you introduce foreign substances, you aren't just adding slide; you're changing the biological environment. Some household items act like a petri dish for bacteria. Others contain alcohols that cause microscopic tears. If you're using condoms, the wrong choice can literally dissolve the latex in seconds.
The Kitchen Cabinet Dilemma: Are Natural Oils Okay?
Honestly, the "natural" label is a bit of a trap. Just because you can eat it doesn't mean it belongs inside your body.
Coconut oil is the most common "pantry" substitute people swear by. It’s a saturated fat, which means it stays slippery for a long time without getting tacky. It smells like a vacation. However, Dr. Jennifer Gunter, a renowned OB-GYN and author of The Vagina Bible, has often pointed out that oil-based products can trap bacteria against the vaginal wall. If you are prone to yeast infections or Bacterial Vaginosis (BV), coconut oil is a gamble. It’s also a total nightmare for latex. If you use a latex condom with coconut oil, the oil breaks down the molecular structure of the rubber. It will break. Period.
Olive oil is another frequent flyer. It's thick. It lasts. But it’s also comedogenic, meaning it can clog pores. In the context of sexual health, it can lead to folliculitis (inflamed hair follicles) around the vulva or anus.

Then there’s the issue of cleanliness.
Water-based lubes wash off with a quick splash. Oils? They linger. They stain your sheets, they ruin your expensive underwear, and they stay on your skin long after the fun is over. If you must use an oil, make sure it is a high-quality, cold-pressed vegetable oil with no added scents or preservatives. But even then, keep it away from latex.
Why You Should Avoid Lotion and Baby Oil
Don't do it. Just don't.
Most hand lotions contain perfumes, parabens, and alcohols. These are fine for the calloused skin on your elbows, but they are "hot" on sensitive tissue. It burns. You might not feel it immediately, but ten minutes in, you’ll realize you’ve made a mistake. The fragrance alone is enough to send your pH levels into a tailspin.
Baby oil is even worse in some ways. It’s mineral oil-based. While it’s incredibly slippery, it’s also incredibly difficult for the body to flush out. Studies have suggested that using mineral oil internally is linked to higher rates of BV because it creates a film that prevents the "good" bacteria (lactobacilli) from doing their job.
The Science of "Slip": Why Specialized Lube Wins
When you buy a product specifically labeled as personal lubricant, you're paying for three things: pH matching, osmolality, and safety testing.

- pH Balance: A healthy vaginal pH is typically between 3.8 and 4.5. Most soaps and lotions are way more alkaline. Using them is like dumping bleach into a swimming pool—it kills the balance.
- Osmolality: This is a nerdy term for the concentration of particles in a liquid. If a lube has high osmolality (like many cheap, glycerin-heavy drugstore brands), it actually sucks water out of your cells. This leads to tissue dehydration and irritation.
- Compatibility: Professionals test these products with latex, polyisoprene, and silicone to ensure they don't degrade the material of condoms or toys.
If you’re looking for what to use as lube and you have the choice, go to a store. It's worth the trip.
Water-Based vs. Silicone: Which One Do You Actually Need?
It depends on what you're doing.
Water-based lubricants are the "everyman" of the sex world. They are safe for all toys, all condoms, and all bodies. The downside? They dry out. You have to reapply. Brands like Sliquid or Good Clean Love focus on "iso-osmotic" formulas that mimic natural arousal fluid. They don't feel sticky, and they won't leave you itchy the next day.
Silicone is a different beast. It doesn't absorb into the skin, so it stays slippery forever. You can use it in the shower because it isn't water-soluble. It’s great for anal sex because that area doesn't produce its own moisture.
Wait! Huge caveat: You cannot use silicone lube with silicone toys. The lube will "melt" the surface of your toy, creating tiny pits where bacteria can hide. It’s a chemical reaction you can't undo.
Household Items That Are Absolutely Off-Limits
We’ve all heard the urban legends. Let’s clear them up.

- Vaseline/Petroleum Jelly: It’s too thick, it’s not water-soluble, and it’s been linked to increased risks of infection. It also eats through condoms faster than you can imagine.
- Spit: Everybody does it. But honestly? Saliva contains digestive enzymes and bacteria. It’s also not very slippery once it starts to evaporate. It’s "fine" in a pinch for a second, but it’s a poor substitute for actual lube.
- Shortening/Butter: It’s food. Keep it in the kitchen. The fats in dairy or vegetable shortening can go rancid and lead to serious inflammatory issues.
- Soap/Conditioner: The surfactants in soap are designed to break down oils. Your body needs its natural oils. Putting soap inside you is a recipe for a burning sensation you won't forget.
What to Use as Lube If You Are Trying to Conceive
This is a specific niche that most people forget about.
Standard lubricants—even the "healthy" ones—can act as a barrier for sperm. They change the acidity of the environment or are simply too thick for sperm to swim through effectively. If you are trying to get pregnant, you need a "fertility-friendly" option like Pre-Seed. These are formulated to match the pH of cervical mucus during your fertile window, giving the little guys a fighting chance.
Practical Steps for Choosing the Right One
Look, the best thing to use as lube is actual lube. If you're stuck and desperate, a small amount of plain, organic coconut oil is the "least bad" household option, provided you aren't using latex condoms or toys.
But if you want to do it right, follow these steps:
- Check your tools: Using a silicone toy? Buy water-based lube. Using a latex condom? Avoid anything with "oil" in the ingredients list.
- Read the back of the bottle: Avoid glycerin and parabens if you’re sensitive. Glycerin is a sugar, and sugar feeds yeast. Not ideal.
- Do a patch test: Put a drop on your inner arm. If it gets red or itchy there, keep it away from your more sensitive bits.
- Think about cleanup: If you hate oily stains on your sheets, stick to water-based. It’s easier on the laundry.
If you find yourself frequently reaching for household substitutes, it might be time to just buy a high-quality bottle and keep it in a dedicated spot. Your body will thank you for not treating it like a science experiment.
Invest in a product designed for the job. Look for "pH-balanced" and "iso-osmotic" on the label. Brands like Sliquid, Uberlube (for silicone), and Aloe Cadabra are generally regarded by pelvic health physical therapists as the gold standard. They might cost more than a tub of Crisco, but they save you a lot of money in doctor's visits later.
Clean up immediately after using any oil-based substitute. Use a mild, unscented soap on the outside only. Never douch or try to "wash out" the inside; your body has a self-cleaning mechanism that works best when left alone. Just wipe away the excess and let your natural flora recover.
