Lillieperl, that's good advice. We've used lubricants for fun for years before they became more of a pragmatic thing.
If it was ever a "performance problem" for anyone, it was my H. All he could see was "I used to make her wet at the drop of a hat, and now I don't". It took a number of repetitions of "it's perimenopause, not you" before he really believed it, I think.
I don't particularly like Astroglide though, it seems sticky to me and doesn't taste very good. Our current favorite is Shunga, but there are others out there that are nice, too. (Don't care for the flavored ones though, expecially cinnamon - blech!).
