Safer sex is a general term used to describe methods for reducing the chance that you will spread or catch sexually transmitted diseases (STDs, also known as sexually transmitted infections or STIs). The idea is that with a few simple tools and strategies, you can increase safety without sacrificing your sex life.
The first and best line of defense is to use a latex barrier whenever you have sex (if you have a latex allergy, use polyurethane instead). That means using a condom on the penis or on a sex toy; latex gloves on your hands; and when engaging in oral sex, dental dams or plastic wrap to cover the anus or vagina.
Get tested for HIV and other STDs
Knowing your own status is the only way to approach the next point honestly.
Safer sex also involves talking with your partner, discussing activities and risks and making educated choices together. Of course, sex raises a number of other questions. Do you trust your partner? How do you get a guy to use a condom if he refuses to do so? What if you are suspicious that your partner is not being monogamous?
Change sex practices
Some people choose to avoid risky activities completely or find ways to reduce the complications associated with themalthough this strategy still requires honesty, communication, and STD testing.
Be monogamous or abstinent
Total abstinence is the only 100% effective safe sex method; it's just not that realistic for most people. Next in line is a long-term monogamous relationship in which both partners know their status to be negative for STDs (itself requiring testing and honest communication), and both stay true to the monogamous ideal.
