Hi,I am 28 years old. I had very happy sexual relationship 8 years ago which lasted for 7 months. We had vaginal, anal, oral sex and she used to swallow my cum. I have a 5 inch penis. When we had missionary style sex, I used to go deep in but in doggy she didnt feel much pleasure. We had great days. She got married and went her way. And I didn't contact her after.Now, begins my story. 2 years ago, I got to know that I have HIV since 2005. I had been having this sexual relation with her in the year 2010. I felt very bad after knowing about my status. My guardian didn't inform me about my status fearing that I would become mentally sick after knowing this.I felt emotionally bad about having sex with her, knowing about my HIV. But I did not know about this earlier. I felt guilth that I had destroyed her Life.2 month ago, I saw her after many years. She is happily married and has 2 kids. She is looking more gorgeous than before. She looked at me and smiled but I pretended I did not see her. My heart said that she has not got HIV and I felt relief seeing how happy she was.My questions are:1. We never used condoms during Sex, then how she is lucky not to get HIV?2. I always ejaculated inside her vagina. How she survived?Is it because of zero viral load?
