How to protect yourself
Abstain from sex or postpone first-time intercourse for as long as possible.
Know the signs and symptoms of the common STD, such as genital discharge, blister, sore or rash.
Have sex with only one person who only has sex with you.
Use a barrier, like a condom, and a spermicide containing nonoxynol-9 each time you have sex.
Tell your partner if you are showing signs or symptoms of STD, and don't have sex until you and your partner both are cured.
Go to a clinic or see a doctor right away if you or your partner have STD signs or symptoms.
Have a regular STD checkup by a clinic or doctor if you have more than one sex partner.
If you think you are pregnant, get a test for STD.
