Just Need to Vent

So this past week my boyfriend has been having some weird symptoms with his genitals. And any time he would try to talk about I would avoid the topic because its terrifying. This weekend it blew up. It started with doing research on STDS and it turns out that his symptoms line up with the possibility of herpes. So we either had this before we started dating or one of us has cheated. And he instantly assumed that I have cheated. I go to parties every now and then but I couldn't ever possibly cheat on him. And I know he couldn't cheat on me. Then after I cried and cried about the research, seeing what herpes are, and him asking if I've cheated. He confessed to me, after 8 months of dating, I'm his first in every department: first girl he has ever kissed, touched, seen naked, had sex with, dated, and loved. I knew about being his first girlfriend but before we started dating me told that he has 6 partners before me. So this was all so shocking and I just felt weird. He had explained that he never told me because he was embarrassed and nervous. So ya our relationship was thrown in a loop this weekend. We're getting tested on Wenesday to see what's going on.
