i don't know anything about you like your age to know if this problem is hormonal or not but until you have a chance to see your gynecologist for patient-specific advice i would suggest that you use one of the many sexual lubricants available over-the-counter. and your partner needs to take time with adequate foreplay to allow you to naturally lubricate before intercourse. just have the guy your with spit on it. nothing like good ol saliva to get the job done.
