With so much focus on saliva during oral sex, one sex expert says there's another liquid you should be thinking about: lube.
According to sexologist and author Jessica O’Reilly of The New Sex Bible, your oral sex game will change if you use the wet stuff.
"Most people rely on their saliva alone for oral, but your technique repertoire grows exponentially if you add the slippery stuff," she tells The Huffington Post Canada.
When shopping for lube, O’Reilly suggests sticking with the natural stuff. This way your lube is clear of added fragrances or flavours.
Safe sex advocate and condom expert Melissa White notes there are generally two types of lube: "Water-based lubes are slippery and may need to be reapplied [and] silicone-based lubes are slick and can be used in water."
O’Reilly says when you're going down on your partner, add lube to your fingers to create a second tongue sensation.
"You can [also] squeeze some in your hands and let it drop over your partner's hot spots... or you can slide some over your lips before heading downtown."
She also suggests checking out other sex toys or props like brushes and using lube to "paint" over your partner's genitals.
