How many times can you get HIV through sexual intercourse?

　　The risk of contracting HIV does not depend on the number of sexual intercourses you have, but rather on a variety of factors, including whether you used safety precautions (such as condoms) and the likelihood of having sex with an HIVinfected partner.

　　1. Safety precautions: Unsafe sex (i.e., not using condoms) significantly increases your risk of contracting HIV. Using condoms can significantly reduce this risk.

　　2. HIV status of your sexual partner: If your sexual partner is HIVpositive and not on effective treatment, the risk of transmission increases. If an HIVinfected person effectively controls the virus through antiretroviral therapy (ART), the likelihood of transmitting the virus to others is greatly reduced.

　　3. Type of sexual behavior: The risk of contracting HIV varies with different types of sexual behavior. For example, the risk of anal sex is generally higher than vaginal sex, while the risk of oral sex is relatively low.

　　4. Multiple sexual partners: Having sex with multiple sexual partners increases your risk of being exposed to HIV, especially when unprotected.

　　5. Other sexually transmitted infections (STIs): If your partner has other sexually transmitted diseases, the risk of contracting HIV also increases.
