When you're planning for a hot night under the sheets, you might not want to think about STDs. If you're happily smitten with your long-time partner, you may not think you have to.
But the possibility of infections and diseases are as much a part of sex as the fun is. Both men and women get them. Even if you didn't realize it, you've probably had an STD.
Knowledge is power when it comes to your sexual health. Recognizing the symptoms is a start, but you won't always notice chlamydia, gonorrhea, herpes, and other STDs. You'll need to get tested to protect yourself -- and your partner. Fortunately, all of these common STDs can be treated, and most can be cured.
Nearly every sexually active person will have HPV at some point. It is the most common sexually-transmitted infection in the U.S. More than 40 types of HPV can be spread sexually. You can get them through vaginal, anal, or oral sex. You can get them by skin-to-skin contact, too.
Most types of HPV have no symptoms and cause no harm, and your body gets rid of them on its own. But some of them cause genital warts. Others infect the mouth and throat. Still others can cause cancer of the cervix, penis, mouth, or throat.
Chlamydia is the most commonly reported STD in the U.S. It's spread mostly by vaginal or anal sex, but you can get it through oral sex, too. Sometimes you'll notice an odd discharge from your vagina or penis, or pain or burning when you pee. But only about 25% of women and 50% of men get symptoms.
Chlamydia is caused by bacteria, so it's treated with antibiotics. After you are treated, you should get retested in three months, even if your partner has been treated as well.
