Viscosity: it matters, and you can change it!
You know that weird thing semen does when it comes out thick and gooey, then becomes a little runnier? That’s thanks to a protein called semenogelin, and it exists to help your load stick to a woman’s vagina and impregnate her, according to Werthman.
“Enzymes made by the prostate fluid eventually break down the gel and make it less viscous, so the sperm can swim out.”
What if your cream’s a little too thick? Try cough syrup. For real! “Something like cough syrup can make [semen] less viscous, just as it makes other secretions less viscous,” Werthman says, though probably it’s not a good thing to drink cough syrup just to thin out your semen?
