Risks: HIV and STIs After Unprotected Contact - Urology

HIV Issues


I visited a sex worker last week.
During our encounter, I used a condom, but since I couldn't ejaculate, she removed the condom and used lubricant to masturbate me without washing her hands.
Is this a risky action? I have developed non-itchy blisters on my arm.
Could this be syphilis or HIV, or is it unlikely to show symptoms so quickly?

Hello, many sexually transmitted infections (STIs) are transmitted through contact with bodily fluids.
As long as there are breaks in the skin, bacteria or viruses have the opportunity to invade.
Early syphilis or HIV infections can be difficult to diagnose based solely on skin manifestations.
Please seek medical attention for serological testing.

When it comes to understanding the risks associated with HIV and other sexually transmitted infections (STIs) after potential exposure, it’s important to consider several factors, including the nature of the contact, the use of protection, and the symptoms you may be experiencing.

In your situation, you mentioned that you had sexual intercourse with a sex worker while using a condom, which is a significant step in reducing the risk of HIV transmission. However, the fact that the condom was removed and manual stimulation was performed without washing hands introduces a potential risk, especially if there were any bodily fluids involved.
HIV is primarily transmitted through specific bodily fluids: blood, semen, vaginal secretions, and breast milk. The virus is not transmitted through saliva, sweat, or urine. Therefore, the risk of HIV transmission from hand-to-genital contact is generally low, especially if no blood was involved and the skin was intact. However, if there were any cuts or abrasions on your hands or the sex worker's hands, the risk could increase slightly.

Regarding your concern about the water blisters on your arm, it’s essential to note that symptoms of STIs, including HIV, typically do not appear immediately after exposure. The window period for HIV can range from a few weeks to several months, during which the virus may not be detectable. Common early symptoms of HIV infection can include fever, fatigue, and swollen lymph nodes, but these symptoms can also be associated with many other illnesses. Water blisters that are not itchy could be related to a variety of conditions, including allergic reactions, infections, or other dermatological issues, and are not specific indicators of HIV or syphilis.

If you are worried about the possibility of having contracted HIV or any other STIs, the best course of action is to get tested. Many clinics offer confidential testing for STIs, including HIV, and can provide you with the necessary information and support. Testing is particularly important if you have engaged in any activities that could pose a risk, even if you are not currently experiencing symptoms.

In summary, while the use of a condom significantly reduces the risk of HIV transmission, the removal of the condom and subsequent manual stimulation without washing hands does introduce some risk, albeit likely low. The appearance of water blisters on your arm is not a definitive sign of HIV or syphilis, especially if they are not itchy. It is advisable to consult a healthcare provider for testing and further evaluation to address your concerns and ensure your health and safety. Remember, practicing safe sex and regular STI screenings are crucial components of sexual health.
