Like many others before me I am a guy who has made a few stupid decisions. I occasionally have engaged in some low-risk sexual activities for the last 3-4 years. I was tested for all the STDs including HIV less than 2 years ago. However, over the last 1 year. I have done a couple of dumb things. I had sex, which was completely protected with a middle aged woman (whom I am almost positive does not have any STDs about 10 months ago. 6 months ago I went to an AMP and paid for a massage and got full service, which I was really not expecting. But everything was completely protected and it only lasted about 5 minutes. Around 2 years ago (5 weeks before my HIV test) a random drunk black woman performed oral sex on me for about 1-1.5 minutes. Finally just a few hours ago, I picked up a 40 year old Latina who took $50 from me for drinks and then took me back to her place and had sex with me. This episode was completely protected, but she did seem a bit "slutty" to me. We did make out twice for 10-15 seconds each. The episode lasted for about 12 minutes. I am most concerned about HIV and Hep B/C. Please let me know what my risks are for HIV and Hep B/C, I hope it is close to or virtual zero since all intercourse (vaginal only) was completely protected. I don't want to get tested again because I am currently a grad student and I have a lot on my plate. Also, should I get HIV prophylaxis, which I don't want to get because of its dangerous side effects and my busy schedule??? Please let me know soon, I am worried and would appreciate the info.
