I'm looking for a new lube for use with silicone toys. I love the feel of Sliquid Organic, and I hear it's one of the better ones for sensitive women. But every time I use it I get a terrible reaction - itching + fissuring on my vulva. (It feels like a vulvar yeast infection, but I thought Sliquid wasn't supposed to encourage yeast because it's glycerine-free?) Any suggestions? I just bought KY Silk and it hasn't bothered me the one time I used it, but I'd like a lady-friendly and environmentally-friend ly brand.
