Intro Music Laci Green: Oh hey babes, let's talk about lube Lube is my favorite. Number one, top (pause) model. Uh, no. Top liquid (laughs) Lube is great it makes everything during sex feel better than it already felt It can soften your skin, reduce genital irritation and it can change the taste of oral If you want it to. I don't usually want it to. There are three main types of lube
Water, Oil and silicone based You can tell which it is by looking at the la oh (ops bottle) By looking at the (giggles) god (ops bottle) By looking at the label Now each of these types has pros and cons so here's the run down Water based lube is compatible with all the condoms, all the body parts, it's cheap it doesn't stain But it ies out the quickest Now if you're doing the sexy and your water based lube does y out
Instead of adding more lube, try adding more water to make this kind slippery again Silicone based lube is compatible with all the body parts, all the condoms And it lasts longer than water based lube It's actually my favorite Sillicone based lube is completely safe it does not get absorbed by the body It also doesn't stain although you may have to wash the sheets But let's be real, you probably had to do that any way It's also great for helping folks with chronic yness and genital pain
The downside is that it tends to be more expensive and you can't really find it on ug store shelves (shrugs) I haven't And it can't be used with silicone toys. It will definitely melt them. Because science Oil breaks condoms and it stains It can also trap bacteria inside your body which can cause yeast infections and bacterial vaginosis (Sarcasm) So you know just a lot of great things going on with oil based lube But it is okay with some hand to penis action Just make sure it doesn't getyour pee hole So the take away here is that not all lubes are created equally
And that goes not just for the type of lube, but also for the brand and specific formulation Commercial Lubes are typically um (makes tsking sound) How to say thisé shitty. My professional opinion is that too many lubes on the shelves are loaded up with a bunch of crap that causes problems And when I'm using lube, I just wanna have good sex. Not problems Here are things that you should look out foryour lube Glycerin! It'stons of lubes It acts like a sugaryour body. Which can cause yeast infections It gave me yeast infections for two years before I figured that one out.
(Sarcastically) Yay. Polyquaternium compounds. These are foundmany formulations of Astroglide as it turns out. and it's been found by the World Health Organization to increase HIV 1 repliion. Hmm Propylene Glycol, Parabens, Nonoxinal9 The ingredient party just goes on and on I'll put a linkthe description so you can read up The last thing to pay attention to, besides, you know, how it feels when you actually use it
Around six months ago I made a tutorial goingover the different types of sex lubricants and their uses. I talked a little bit aboutquestionable ingredientsthat tutorial, but today I really want to get into the scienceyside of lubricant safety, specifically the issues of osmolality and pH. There's a lotto learn, but I'm going to try to keep it really simple and just basically introduceto common causes of irritation and how to avoid them. Osmolality is sometimes referredto as the quot;concentrationquot; of a solution. It's the measure of dissolved particles per unitof water. The osmolality of a waterbased or hybrid lubricant is super important becauseit can affect the homeostasis of your nether
regions' mucous membranes. It's a hyationissue, basically. If something has a lower osmolality (i.e. a higher concentration ofwater) than your body's natural cells, then your cells are going to pull water from it.Too much water, and your cells can actually rupture. And if something has a higher osmolalitythan the body, it's going to pull water FROM your cells, dehyating and potentially killingthem. A study published2008the American Sexually Transmitted Diseases Association'sofficial journal found that the osmolality of a lubricant is closely linked to its potentialfor mucous membrane irritation. Hypoosmotic lubricants, with a lower osmolality than thebody, caused negative mucus production in
test subjects, while hyperosmotic lubricantscaused irritation and tissue damage proportional to their level of osmolality, up to quot;severedamagequot; from the worst offender Astroglide. A 2006 study conducted by a research teamled by Craig W. Henix, a al pharmacologist at Johns Hopkins, found that hyperosmotic lubricantID Glide caused significant rectal tissue damagehumans and may actually increasesusceptibility to HIV and other STIs. For comparison purposes, the average osmolalityof vaginal mucus is between 260 and 290 mOsmkg, while human semen is between 260 and 380.The osmolality of popular commerciallyavailable lubricants, on the other hand, is often over2000, even surpassing 10000 mOsmkg. Isosmotic
lubricants, which are similar to the body'snatural osmolality, have been found to be the safest, causing little to no change inthe mucous membranes of test subjects. Now, what does that mean for a consumeré Obviouslymost of us can't test the osmolality of our lubes ourselves, so how do we know what'ssafe to useé Well, the first step is to learn what ingredients are typically foundhyperosmoticlubricants. The two biggest ones are propylene glycol, a rochemical, and glycerin, a sugaralcohol that acts as a humectant. Just seeing one of those ingredients on a lube packageis an immediate indiion that the product is likely hyperosmotic, and most widelyavailablelubricants contain both. So that's not great.
Brands that come closest to ideal osmolalityinclude Good Clean Love, Sliquid, and Aloe Cadabra. I'm sure there are others, but unfortunatelya lot of brands haven't been tested or haven't publicized their osmolality, so I don't havenumbers for them. If you've ever taken a chemistry class, you've probably heard the term pH,which is the measure of the acidity or basicity of a solution. Various areas of the body havedifferent pHs, and the body regulates all this itself with a balance of natural bacteria,fungi, and body secretions. A balanced pH is important to avoid infection, but foreignsubstances can throw it off balance. That's one of the reasons that you'll hear that youshouldn't use soap inside of the vagina. It
can cause a pH imbalance, which can lead toa yeast infection or bacterial vaginosis. Waterbased and hybrid lubricants can do thesame thing. Vaginal pH tends to fluctuate between 3.8 and 4.6 or a little bit higherdepending on the circumstances. The pH of rectal fluids tends to be between 6 and 8.It's best to use a lubricant that's similarpH to the area you're using it in. Tooacidic and the lube can sting. Too basic and it can cause a bacterial infection. Unfortunately,lube pH also doesn't tend to be very publicized. Lubes with a pHthe range of vaginal safetyinclude, again, most Sliquid lubes, Good Clean Love Almost Naked, Aloe Cadabra, as well asYes and Blossom Organics brand. Lubesthe
