So glad you were able to figure that out. All lubes are not created equally! The most common allergic reaction is to the silicone lubes because of their synthetic components. Glycerin and propylene glycol can also cause issues because of the higher osmolality (the given concentration relative to water) of the product. If the osmolality is high, the lubricant might pull water from the cells (e.g., the cells that make up the lining of the vaginal wall), causing the cells to shrivel, and this can lead to irritation.
