A dry vagina can show that a female is not sexually aroused, has not had enough foreplay or her mind is not ready for sex. There are other causes of dryness such as breastfeeding, diabetes, menopause and some infections such as candida. Dryness can cause pain during sex. To prevent it wait until your mind is ready for sex or have more foreplay. Some lubricants make condoms less effective so read the package carefully. If this does not work go to a clinic to check for infection.
