So me and my girlfriend were discussing about how can we improve cunnilingus, since she is having trouble getting wet. We came up with an idea to get flavoured oral lube. Today I got it from the sex shop, I specifically asked the specialist in the store which one can I use for cunnilingus. I bought what she recommended and got home. Then I decided to search up the web on how to use oral lube. I discovered that oral lubes, which contain glycerine are sometimes not safe to use on vaginas. My recently purchased oral lube contains glycerine. So did I waste my money for nothing or is it not big of a deal? Should I throw it out?
