I am an Eighteen Year Old, Heterosexual Male, On February 5, 2011, I had protected vaginal sex and unprotected oral(She did it to me) with a girl I hardly know from my high school, my first encounter for about 2 years. She was a sort of a ***** from what I knew however, she has had many unprotected sexual encounters before, but I choose I to wear a condom even if she asked me if I wanted to go without one. I do know that oral carries almost no risk, but I still worried a bit because she had braces, no visible blood however. My problem is the type of condoms I had, un-lubricated Trojans, while they dint break and it says protects against HIV/AIDS, and I used more than one during our encounter. I hear they have to be used with a lubricant, does it make much of a difference?. I dint use a lubricant however, I dint have any, her natural fluid was enough I thought to provide the moisture, and it was the only condoms I had at my disposal, after around 3 hours I did not reach a climax(might have been because of the un-lubricated condoms), but she orgasmed and spilled fluid on the base of my penis. I had to take her home, but clean myself up as soon as I arrived back. Should I stop worrying for my safety, Did I protect myself enough, with the type of condom? I have been medically diagnosed in the past as a hypochondriac and HIV is yet another disease I worry about, because of this I don't have many sexual encounters, and basically has ruined my sex life. I donate blood every 3 months, and take tests as much as possible but this time I am more worried than ever, should I even bother wasting the money for a HIV test?. Thank you for your time, and greatly appreciate an answer.
