You Asked It: Let’s Talk Lube

What’s the deal with lube? Do I really need more than what’s already on the condom?

Great question! Lube is a big part of a lot of people’s sex lives, but often goes undiscussed—which is a real shame. Here’s what you need to know.

What is Lube?

Lube (or personal lubricant) reduces friction during sex (of all kinds) to make it comfier, safer and more enjoyable. Some lubes are gels, others are liquids, and some are creams. You don’t necessarily have to use lube for sex, but some people find sex uncomfortable without it.

When vagina-havers get aroused (or turned on), their vagina and cervix usually produce some natural lubrication, which we talk more about here. This is what getting “wet” means. Different bodies make different amounts of lubrication. This is why some vagina-havers need lube and others don’t. If you have a vagina, you may find that you need lube only sometimes, or don’t need it now but do when you’re older. That’s all completely normal.

There is NO reason to feel guilty, bad or embarrassed about how much lubrication your body makes—whether it’s a lot, some, or barely any. Using store-bought lube is super normal, and there’s no reason to feel embarrassed about it. And even if you don’t need lube, some people find it makes sex more enjoyable anyway!

As you mention, many condoms already have some lube on them, and that might be plenty. However, if you or your partner finds sex uncomfortable or painful (or you just want to try it out), using extra lube isn’t a bad idea. It’s all about your (and your partner’s) needs and preferences.

Types of Lube

There are three different kinds: water-based, silicone-based, and oil-based.

Water-based lubes are your safest bet if you’re not sure where to start. They don’t break down condoms or toys and they’re easy to wash off. They also don’t stain sheets, are easy to clean up, and are usually cheap. However, water-based lube doesn’t last as long as silicone-based lube, so you may have to re-apply it more. It’s also no help in the shower (it’ll rinse right down the drain) and can be sticky.

Not all water-based lubes are clearly marked. To double check, look at the ingredient list. Water should be one of the first ingredients. If you see “silicone,” “petroleum,” or “oil,” it is NOT water-based.

Silicone-based lubes ruin silicone toys, but they’re safe to use with condoms. Silicone-based lube also lasts longer than water-based, so you don’t have to re-apply it as often. Some people like that it feels silky and **luxurious**. It also doesn’t rinse off in water—which is great for shower sex but annoying to clean up—and isn’t as sticky. Most silicone-based lubes are clearly labeled, but look for “silicone” in the ingredient list if you’re unsure.

Oil-based lubes should NOT be used with condoms. The oil breaks down the latex, and can make your condom tear, putting you at risk for sexually transmitted infections (STIs) and potentially pregnancy. Since it sounds like you’re using condoms (which is great!), stay away from oil-based lubes. This means no Vaseline/petroleum jelly, cooking oils, coconut oil, baby oil, or body lotion. Very few products marketed as personal lubricants are oil-based. Even if you don’t use a condom, oil-based lubes can still trap bacteria and cause infections, and they can stain bed sheets.

If you have sensitive skin or allergies, look for lubes with shorter ingredient lists and spot test the lube on your wrist or some other exposed skin.

Where to Get Lube

You can buy lube at most drugstores in the “family planning” or “sexual health” aisle, or online. It can be as cheap as $5, though some can get pretty pricey (especially silicone-based ones). You can also get free packets of lube at many community health clinics and Mount Sinai Adolescent Health Center.

How to Use Lube

Some people with penises like to put a drop inside the tip of the condom before putting it on to increase sensitivity.  If you’re having penis in vagina (PIV) sex, you can put a little on the outside of the condom, around the vaginal opening, and just inside the vagina. For fingers and toys, same basic idea—put a little on your fingers or the toy, around the vaginal opening, and just inside the vagina.

If you’re having anal sex (with a penis, fingers, or toys), ALWAYS use lube. The vagina produces some natural lubrication, but the anus does not. This means that without lube, anal sex can create lots of friction and tiny tears. These are entry-points for STIs, and they can make anal sex painful—which is no good. Sex should be a fun, pleasurable experience for everyone.

Spit is usually enough lube for oral sex, but it’s completely safe to use store-bought lube if you want to—it just might taste bad. You can use flavored lubes (and condoms!) to help. Just be careful if you have a vagina—many flavored lubes have sugars and other ingredients that can lead to infections if you have sensitive skin or don’t wash it all out of your vagina.

You can’t technically use too much lube, but some people find that using a LOT decreases sensitivity and makes sex less pleasurable. Start with a little and build up to a point that works for you and your partner.
