So, I am pretty worried. My ex boyfriend found out he had AIDS. And I had sex with him. Everytime I did it was protected and we only dated for about a month and we only had sex maybe 6 or 7 times. This whole situation took place about three years ago. I haven't had sex with him since. I actually got STD tested including HIV tested about a month ago and it came up negative. I don't even know if he had it when we had sex but I am really worried. Do you think it is possible that I could have it and it not show up because I heard it takes many years to show up. Someone please clear it up because I am worried.
