I am using Replens and have found it quite good. I always have to use lubricant for sex though, have needed to for years.
However, the best thing I have found to help the dryness especially around the vaginal entrance and to stop the constant urinary tract infections has been to stop using anything except sorbolene cream in the shower to wash my genital area.
This was recommended to me by my Pharmasist and I was sceptical at first, but for me it has done wonders.
It has also helped with discomfort during sex.
