Water-based[ edit ] Water-based personal lubricants are water- soluble and are the most widely used personal lubricants. The earliest water-based lubricants were cellulose ether or glycerin solutions. Products available today may have various agents added for even dispersal, moisture retention, and resistance to contamination. The viscosity of these products can be altered by adjusting their water content and concentration of cellulose or other gel-forming hydrophilic ingredient. Because water-based personal lubricants absorb into the skin and evaporate , most water-based lubricants have a tendency to dry out during use, but reapplication of the lubricant or application of water or saliva is usually sufficient to reactivate them. When the lubricant eventually dries out, it may leave behind a residue derived from the other ingredients in the formulation.

A Indiana University study found that 65 percent of women have used lubricant to make sex more comfortable, more pleasurable, or both. And in a survey of gay men in San Francisco who have anal intercourse, 89 percent said they always use lubricant during sex. How safe are lubricants?

When the infamous birther scam was launched on Breitbart, even Breitbart said there was no evidence that it was true but because Breitbart readers wanted to believe it, it was accepted as gospel.

well when you think about it I feel that battlefield 1 was worse than this one because the war story is meant to be very good and I am a big fan of War Stories. What do u think?
