I am a 20 year old female who has engaged in heterosexual intercourse only twice- once with one male, and once with another. Both were protected, but the unknown status of my last partner, who happens to be my boyfriend, makes me very anxious. He is a 19 year old male, who has had many partners in his youth- but assures me he tested negative before intercourse with only two other girls before me (one who has recently had a baby, and another (his girlfriend of 2 years) whom I knew to be a virgin). Because one became pregnant and one was a virgin, I assume both are negative; however, i am most concerned about his one encounter with heroin. He assures me it was a clean, unused needle, and only happened once (resulting from his severe depression at one time), but his words aren't enough to satisfy my extreme anxiety. We engaged in intercourse before I was aware of his past- it was protected and lasted only 2 minutes because of my unexperienced pain. He did not ejaculate, but I remember an amount of preseminal fluid in the condom after use. Since then, we have only engaged in casual and open-mouth kissing, hickeys here and there, and he has fingered me on occassion because that is all I will allow him to do until he goes to get tested. Are these behaviors a risk of transmission? At first, he took offense to my request and refused to go (which made me even more anxious) but he has finally agreed as he knows how serious i am about my health. Our very brief intercourse was was 6-7 months ago, and I have been paralyzed by fear ever since. I have since had a pelvic exam, pap smear, and blood work (all with normal results) but what exactly do those detect? do those normal results confirm me to be negative and of overall health? My hypocondria and anxiety causes me to research anything and everything on the matter, I overanalyze each ache and pain and begin to identify myself with symptoms. Are these symptoms simply due to my anxiety or a possiblity of infection? *Also, what is the concentration of the infection in preseminal fluid, in case I was exposed before the actual intercourse? I do appreciate your time and consideration...I hope you may give me the peace of mind I need to return to living my life...
