Is it possible to get pregnant the first time I have sex?

Yes, any time a girl has vaginal sex with a guy, she is at risk for becoming pregnant. Even if a guy ejaculates outside of but near the vagina or pulls out before he comes, a girl can get pregnant.

It's also possible to get a sexually transmitted disease (STD) anytime you have sex, including the first time. Having any kind of sexual contact (oral, anal, or vaginal) can put someone at risk for getting an STD.

Here are some ways to reduce your chance of pregnancy and STDs:

Abstinence. The only way to completely prevent pregnancy and STDs is to abstain from all types of sex, including oral, vaginal, and anal sex.

Use condoms. If you are going to have sex, condoms are the best way to prevent pregnancy and STDs. Talk with your partner beforehand and say that condoms are necessary, not optional, even if you also use another form of birth control. And always take a back-up condom with you when you go out, to be sure you have one.

If you and your partner had unprotected sex (or a condom broke), see your doctor for pregnancy and STD tests.

If you have ever had sex, or are thinking about having sex, talk with your doctor about birth control options, STD testing, and ways to prevent STDs.
