How do you solve a too wet vagina during sex?

Too wet is a relative term. What some people think is excessive, others do not.

I'm not sure if you realize this but there is a reason women have different vaginal secretions. The "wet" variety is usually during the time you are most fertile. Though, others may be indications of an infection.

There isn't really a cure, unless there is a health problem. You should talk to a doctor about this if something seems concerning to you.
