My regular sexual partner had a baby with me in December. Just before the baby was born, she noticed cysts on her buttocks (three in a triangular position). She recalled seeing one on my right hip which I broke and cleaned with my knife. So she had the doctor test it. She just now told me that, on the day that my baby was born, she was told that she had Herpes. So, now I have been engaging in sexual activity for the past four months with a woman who knew she had Herpes and did not tell me because she refuses to trust me not to sleep with other women. The thing is, she had herself tested when she was four months pregnant (without telling me) and claims that she was clean at that time. However, I had my first experience with an unexplained sore in my genital region (just below my belt) shortly after meeting her in 2008. Can the virus go this long without being detected? I am certain I got it from her as I have had no other partners since I met her, and my first cyst was shortly after my first sexual encounter with her. She is certain she got it from me because of her chosen paranoia. Could the earlier test truly have come negative if she had it for a minimum of three years? Or is it just me?
