Linfit, call Yes (get the number online) and ask them to send you some samples of their new vaginal moisturiser. I'm really reactive and seem to be sensitive to quite a number of things I've tried over the past few months. The samples came in little tubes which clearly are designed to be inserted and squeezed, however, there was no way I was going to do that without seeing if I was going to react first.
I tried my first sample this morning, but just snapped off the top and spread a little around the vaginal entrance which is my dodgy allergic area and so far so good, absolutely no stinging. The Yes water based has a preservative in it which made me squirm, very sore!! The Sylk is fine everywhere except around the vaginal entrance.
We are all so different, all seem to react to different things, I think it's a case of trying it to see if it suits you.
Good luck x
