If you or your sex partner has unprotected sex with anyone else, you are at risk for a sexually transmitted disease, or STD. Ask your doctor to test you for STDs during your annual physical, even if you have no symptoms. If you test positive, your sexual partners will need treatment. It may be embarrassing, but you must tell them they have been exposed. It can be a matter of life and death.
Trichomoniasis is a sexually transmitted disease (STD) caused by a small organism called Trichomonas vaginalis. Women are most often affected by this disease, although men can become infected and pass the infection to their partners through sexual contact.
