3 months, ~95% detection rate. 6 months, ~99% detection rate. They are testing for antibodies, not the virus itself. It is possible to be tested for the virus itself, but you won't be able to get that test.
The likelyhood of getting HIV from one fuck is extremely slim.
I had a bout of neurosis for a few months once. I was convinced I had HIV, even with the knowledge that the likelyhood was less than 1/1000. I thought I was the unluckly one... until a doctor told me I was out of my fucking mind and I snapped out of it.
well if they have aids, I think it's 3 months, for HIV 6 months. That shit fucking scares me every time dude. Just think...you could be negative for 10 years and then all the sudden you have it...fuck that.
