    Could I Have an STD and Not Know It?

    By Terri D'Arrigo

    A one-night stand. A summer fling. A new love interest asks about your sexual history. A long-term partner confesses to cheating on you. Any of these could make you wonder, "Do I have an STD?"

    So you check below the belt. No itching. No sores. No weird oozing or funky smells. It doesn't hurt when you pee. There's nothing obvious that would send you to the doctor. That means you're OK, right?

    Trichomoniasis

    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.

    Not exactly. It's possible to have an STD and not know it. Sometimes symptoms are mild. Sometimes they can be mistaken for other conditions, like when women have discharge from a yeast infection. Sometimes STDs don't have symptoms at all. Yet they can cause health problems.

    Talk to Your Doctor

    "The same way we can have germs on our skin, in our mouths, or in our digestive tracts and not know it, we can have germs on or inside our genitals," says Jeffrey D. Klausner, MD. He's a professor of medicine and public health at UCLA's David Geffen School of Medicine. "The only way to learn if you have an STD is to get a checkup and talk to a doctor or nurse about your sexual health."

    Women usually discuss sexual health with their gynecologists. But both women and men can speak to their regular doctors or nurse practitioners.

    "You don't need to see a specialist. All primary care providers can offer STD tests," Klausner says.
