Doctor Du, is the probability of my behavior high or low?


Hello Dr.
Du, I apologize for bothering you again.
Regarding your response to question (140808), you mentioned that the opportunity is either high or low.
Could you please clarify whether my behavior poses a high or low risk of contracting HIV? Thank you, Dr.
Du! (Hello, yesterday I had unprotected contact where my glans rubbed against the partner's anal area with saliva, but there was no penetration.
Is there a risk of contracting HIV? Thank you.)

Low-risk activities include mutual masturbation, light kissing, mutual rubbing, and condom-protected sexual intercourse.
Moderate-risk activities include deep kissing, oral sex, and withdrawal method (coitus interruptus).
High-risk activities involve unprotected sexual intercourse and any actions that cause wounds or bleeding.
Hello: It is advisable to stay within the low-risk range.
Wishing you good health.

When it comes to understanding the risk of HIV transmission through specific sexual behaviors, it is crucial to consider the nature of the activities involved, the presence of bodily fluids, and the overall context of the encounter. In your case, you mentioned engaging in activities where the glans of your penis came into contact with the anal area of your partner without penetration, and you did not use a condom during this interaction.

HIV is primarily transmitted through specific bodily fluids, including blood, semen, vaginal fluids, and breast milk. The virus is most commonly spread through unprotected sexual intercourse, sharing needles, or from mother to child during childbirth or breastfeeding. The risk of transmission can vary significantly based on the type of sexual activity, the presence of cuts or sores, and whether any bodily fluids are exchanged.

In your scenario, while you did not penetrate, the contact of the glans with the anal area could still pose a risk, albeit lower than penetrative anal intercourse. The risk of HIV transmission through external contact (such as rubbing or friction) is generally considered to be much lower than through penetrative sex. However, if there were any cuts or abrasions on your penis or if your partner had any open sores or bleeding, the risk could increase.

The specific risk of HIV transmission through oral or anal contact without penetration is not well-defined and is generally considered to be low. However, it is important to note that any sexual activity that involves contact with bodily fluids carries some level of risk. If your partner is HIV-positive, the risk of transmission increases, particularly if there are other sexually transmitted infections (STIs) present, as these can facilitate the transmission of HIV.

In terms of your concerns about symptoms, it is essential to understand that many early symptoms of HIV infection can be nonspecific and may resemble those of other viral infections. Common early symptoms of HIV can include fever, fatigue, sore throat, swollen lymph nodes, and rash. However, many individuals may not experience any symptoms at all during the acute phase of HIV infection.

Given your situation, it is advisable to get tested for HIV and other STIs. The window period for HIV testing can vary depending on the type of test used. Generally, it is recommended to get tested at least 2-4 weeks after potential exposure, with follow-up testing at 3 months for more conclusive results. If you are feeling anxious or have any symptoms that concern you, seeking medical advice from a healthcare provider is essential. They can provide guidance on testing and any necessary follow-up care.

In summary, while the risk of HIV transmission through the activities you described is considered low, it is not zero. It is always best to err on the side of caution and get tested, especially if you have concerns about potential exposure. Additionally, practicing safer sex methods, such as using condoms consistently and correctly, can significantly reduce the risk of HIV and other sexually transmitted infections.
