For most non-pathological vaginal dryness, experts usually recommend the use of human lubricants. Currently, more than 67% of couples in the United States use lubricants.

Traditional petroleum jelly oil is a petroleum product. It is usually applied on the surface of the female clitoris or male penis to make it non-drying for a long time. However, this type of oil will stain the sheets, is greasy, and cannot be used with condoms.

The best-selling products in the United States are water-soluble lubricants such as KY glue. This water-soluble lubricant has no chemical activity and can avoid affecting the growth of normal vaginal flora and generally does not cause allergic reactions.

The method of application depends on personal preference and physical condition. The most common method is to apply it on the condom. Secondly, it can be applied to the female vulva, such as the clitoris. Some women like to apply it directly into the vagina. Generally, water-soluble lubricants are less likely to cause allergies and can be used with confidence.
