We all knew was salt was bad for your blood pressure. But it’s also putting you at risk for getting infected with STDs, including HIV.
And all along we were taught to use lube because it meant less risk of anal tissue tearing.
The use of lubricants may make anal sex more comfortable, but they may also increase the risk of spreading sexually transmitted infections, including HIV, researchers said Tuesday. Many experts have been concerned about the potential effects of such lubricants, but there have previously been virtually no studies about how they affect disease.
[…] A partial explanation for the increased risk may have been provided by Charlene Dezzutti, a reproductive science specialist at the University of Pittsburgh, and her colleagues. They studied the effects of six of the most popular lubricants on rectal cells and tissues in laboratory dishes.They found that many of the products had high concentrations of dissolved salts and sugars that draw water out of cells, weakening and even killing the cells. Some of them even stripped away significant portions of the surface epithelial cells on the rectal tissue, the layer of cells that serves as a protective barrier. They also studied the effect of the lubricants on beneficial bacteria in the rectum.
So which lubes should you use? “PRE and Wet Platinum, were shown to be safest for the cells, while Astroglide was the most toxic to cells and tissue. KY Jelly had the worst effect on rectal bacteria, essentially wiping out the entire colony. ID Glide and Elbow Grease had intermediate effects, the team found. None of the lubricants was found to have measurable anti-HIV activity.”
