Syphilis Symptoms and Testing After First Sexual Encounter

First sexual intercourse?

I have a question about syphilis.
Is it possible to have a rash on the glans one week after exposure? Currently, I have a rash on the glans that is not painful or itchy, and I also have a rash on my lips that is not painful or itchy.
Is this something that can occur one week after syphilis infection? This month, I had oral sex with a male partner without a condom, but there was no anal intercourse.
Afterward, I shared this with friends in my circle, and they said the other person was very reckless and dangerous, which has made me very worried and scared.
I'm feeling so distressed that I'm having thoughts of suicide and regret, especially since the other person is a known risk.
What tests should I undergo? How many weeks after exposure should I test for HIV and syphilis?

You should visit a urology clinic for a physical examination by a physician to establish a differential diagnosis.
Additionally, due to unsafe sexual practices, it is recommended to undergo sexually transmitted infection (STI) screening to rule out any risks, and to have regular follow-ups.

When it comes to understanding the symptoms and testing for syphilis after a first sexual encounter, it's essential to approach the situation with both caution and clarity. Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. It can present with a variety of symptoms, and the timeline for these symptoms can vary significantly from person to person.

In the case of syphilis, the primary stage is characterized by the appearance of a painless sore or ulcer, known as a chancre, at the site of infection. This typically occurs about three weeks after exposure, but it can appear anywhere from ten days to three months later. If you are experiencing a rash on the glans (the head of the penis) and on your lips, it is crucial to consider that these symptoms may not necessarily be indicative of syphilis, especially if they are not painful or itchy. However, they could be signs of another infection or condition, and it’s essential to get them evaluated by a healthcare professional.

Given your concerns about having unprotected oral sex and the potential exposure to STIs, including syphilis and HIV, it is advisable to seek medical attention promptly. Testing for syphilis typically involves blood tests that can detect antibodies to the bacteria. The most common tests include the Rapid Plasma Reagin (RPR) test and the Treponema pallidum particle agglutination assay (TP-PA). These tests can usually provide results within a few days.

For HIV, testing is recommended at various intervals depending on the risk factors involved. Generally, an initial test can be done as early as two to four weeks after potential exposure, but it is often recommended to wait at least three months for a conclusive result. This is because the body may take time to produce detectable antibodies after infection, a period known as the "window period."
In your case, if you are experiencing anxiety and feelings of regret, it is crucial to address these feelings with a healthcare provider or a mental health professional. The fear of potential infections can be overwhelming, but it’s important to remember that many STIs are treatable, and early detection is key to effective management.

In summary, if you have developed any unusual symptoms after a sexual encounter, especially if they involve rashes or sores, it is essential to consult a healthcare professional for a thorough evaluation and appropriate testing. Do not hesitate to express your concerns about both syphilis and HIV, as well as any emotional distress you may be experiencing. Taking proactive steps towards your health is the best course of action, and there are resources available to support you through this process.
