Yes, various glands in the vagina produce wetness when a woman gets turned on. That part was fine. No, you were probably not experiencing recurring vaginal infections all the time.
Cervical fluid is to the woman what seminal fluid is to the man.
Since men are always fertile, they produce seminal fluid continually. Women, on the other hand, are only fertile the few days around ovulation, and therefore only produce the substance necessary for sperm nourishment and mobility during that time. Cervical fluid looks and feels almost exactly like raw egg whites in the fertile phase of a woman's cycle. At other times in a woman's cycle, the fluid is creamy, watery, or nonexistent. If you have sex during a non-fertile time without birth control, it's extremely unlikely you will get pregnant.
