I recently changed gynecologists and learned something new to me. She said to use a long-acting lubricant such as Replens at bedtime every three days, otherwise the dryness will cause irreversible changes, making sex and pap smears more painful. I thought I was pretty well-informed, but I did not know about this.
We all need to push the companies that provide these products to "go green" and make them available in suppository form so that we are not discarding applicators into the landfill.
K-Y makes a product, too; I think it's called Ovule. It is a suppository, but it only comes with applicators, which end up in the landfill.
