What kind of sex you want to have is a personal decision. Some sex acts carry a high risk of passing on HIV. With other sex acts, it's not so clear.
 
Unprotected anal or vaginal intercourse is high risk. Oral sex has a much lower risk.

The basic rule for having safer sex is that you don't want your blood, semen, pre-cum or vaginal fluid to get into your partner's body, and you don't want any of his or her fluids to get into you.

You have several choices. You can choose not to have sex at all. Or you can choose to avoid penetration and find satisfaction in other activities. If you choose to have penetrative sex, a latex condom used correctly will reduce the risk. This is called safer sex because it reduces the risk but does not eliminate it entirely.

Since a person with HIV does not look any different, and may not even know they have the virus, it is VERY important that safer sex be followed each time you have sex.

Knowing how to prevent the transmission of HIV is the first step. Making the choices and sticking with them can be difficult - but they can save your life.
