Osmolality and pH can be very mysterious factors when it comes to lube. At least pH can be easily home tested, while osmolality levels remain nearly impossible to find.
A few manufactures do list their osmolality ranges though, and a few specify ‘low osmolality,’ so keep an eye out for it. Another thing to look out for is the presence of glycerin or propylene glycol which predict a high osmolality.
Below are a couple of links from people who were good enough to make spreadsheets on various lubes tested, or published, pH and osmolality range.
I wanted to immediately dive into lube cause it’s one of the single most important things people often don’t realize they need (or realize is causing irritation it shouldn’t).
There’re so many reasons lube can be necessary. These reasons range from asses needing it, to a person being dehydrated, to menopause, to condomed blowjobs, to sex just straight up being more comfortable with lube. Even bodies that make their own, it’s often not nearly as long lasting as a good bottled lube. So over the next four pages Sex Talk is going to cover all things lube.
It’s also STI testing week! Go out an get tested if you can! Even if you don’t think you could’ve contracted anything it’s always good to have documentation, especially since you never know when you’re going to meet someone new who might need to know.
