The situation you've described regarding the transmission of herpes simplex virus (HSV) is indeed complex and can be quite confusing. Let's break down the key points regarding HSV-1 and HSV-2, their transmission, and your specific case.


Understanding HSV-1 and HSV-2
Herpes simplex viruses are categorized into two types: HSV-1 and HSV-2. HSV-1 is typically associated with oral herpes (cold sores), while HSV-2 is more commonly linked to genital herpes. However, both types can infect either area. It's important to note that HSV-1 can cause genital infections, especially through oral-genital contact.


Transmission Dynamics
In your case, your ex-boyfriend has HSV-1, which he has on his abdomen. You mentioned that during intimate contact, your genital area came into contact with his infected skin. While HSV-1 is less commonly associated with genital infections, it can still be transmitted to the genital area through skin-to-skin contact.
However, you later tested positive for HSV-2, which raises questions about how you contracted it. Here are a few possibilities:
1. Pre-existing Infection: It's possible that you had a latent HSV-2 infection that was undetected at the time of your initial testing. Many individuals with HSV-2 do not show symptoms, and the virus can remain dormant in the body for long periods.

2. Cross-Reactivity: While it is unlikely, there can be some cross-reactivity in serological tests. This means that a test for HSV-2 might yield a false positive in certain cases, although this is rare.

3. Transmission from Another Source: If you had any other sexual contact, even prior to your relationship with your ex-boyfriend, it could be a source of HSV-2 infection.
4. Misinterpretation of Symptoms: The lesions you experienced could have been misdiagnosed initially. If they were indeed HSV-2 lesions, it would explain the subsequent positive test.


The Role of Testing
You mentioned that you tested negative for both HSV-1 and HSV-2 initially, which is a crucial point. However, serological tests can sometimes yield false negatives, especially if the infection is recent. The antibodies for HSV-2 typically take time to develop, and testing too early after exposure can lead to negative results.


Emotional and Psychological Impact
It's understandable that this situation has caused you significant distress. The stigma associated with herpes can be overwhelming, and the uncertainty surrounding your diagnosis can exacerbate feelings of anxiety and confusion. It's important to remember that many people live with herpes and manage it effectively.

Recommendations
1. Consult a Specialist: If you haven't already, consider consulting a dermatologist or an infectious disease specialist who can provide more insight into your specific case and help interpret your test results accurately.

2. Regular Testing: Continue to monitor your health with regular testing, especially if you experience new symptoms or changes.

3. Open Communication: If you enter into new relationships, communicate openly with partners about your health status and any concerns regarding HSV.

4. Support: Seek support from counseling or support groups for individuals with herpes. This can help you cope with the emotional aspects of living with a herpes diagnosis.

In summary, while it may seem perplexing that you contracted HSV-2 from a partner with HSV-1, the dynamics of herpes transmission are complex. Understanding the nature of these viruses, the limitations of testing, and the importance of open communication can help you navigate this challenging situation.
