One of the most common primary causes of vaginal pain during intercourse is a dry vagina. Usually, when a woman is sexually aroused, fluids are secreted in the vagina that keep the lining well lubricated. But if a woman is not sexually aroused, or if fluids are not secreted for some other reason, intercourse can cause very painful damage to the vaginal lining. And in some cases, the lining of the vagina can actually tear, resulting in post-intercourse bleeding.
There are two ways to avoid a dry vagina during intercourse. The first is to avoid intercourse until you are sexually aroused. The second way is to use an artificial water-based vaginal lubricant
another common cause of vaginal discomfort during intercourse is bacterial infection. This occurs frequently in women, and you need to take treatment for that. A related problem is bladder infections. While the problem may be in the bladder or urethra, not in the vagina, it often causes discomfort during intercourse.
