Re: HIV worry
Although your activity was high risk, two and half months is pretty much conclusive. It would be very rare for anyone to retest positive after that much time has elapsed. Even though the general recommendation for testing is 3 months, about 99% of people will develop measurable antibodies within 4 to 6 weeks. In the older generation tests, it would often be necessary to wait 3 to 6 months, but that isn't the case today. With that being said, I would recommend testing again in about a month if you know for a fact that the person you had sex with was HIV positive or was in a very high risk group, such as an injection drug user. Again, it is very, very unlikely that you would test positive, but it might be worth it for peace of mind, if nothing else. Otherwise, I don't really think you have anything to worry about. Be very careful with anal sex in the future though...the large surface area of mucous membranes make it much easier for HIV to be absorbed into the bloodstream.
