Sexual excitement can also increase the amount of secretions that are produced. A healthy vaginal discharge is a balance of organisms that helps prevent infections. When this balance is disturbed by stress, illness, douching, or some medications, an infection can occur. Another type of vaginitis is caused by the tiny one-celled Trichomonas organism. The two infections can sometimes occur together.
Symptoms can vary depending on the organism causing the infection.
A physician can identify the infection from its symptoms, or may take a sample of material from inside the vagina to be analyzed in a laboratory. Once the specific cause of the infection is verified, the appropriate treatment can be given. Yeast infections can be treated with antifungal creams or vaginal suppositories. Other infections may require a prescription medication for the woman, and perhaps even her partner, to take. Your hygiene habits can do much to help you avoid vaginal infections and irritations.
