You might try using a vaginal moisturizer. KY (the company that makes the KY Lubricant) makes 3 different varieties. They are supposed to last for up to 4 days. I would think that Wal-Mart or a drug store like Wal-Greens would have them. They should be in the feminine hygiene section, and the boxes are clearly marked as moisturizers, not lubricants. Of course, if you're sexually active, since you have this problem, you should use a lubricant too.
By the way, KY does offer samples of some of their products (not sure about these, though). To check, go to www.ky.com.
If the problem persists, you may need to see a gynecologist- you may need hormones or some other medication.
Hope this helps.
