I'm afraid your own math is incorrect on this one: the rate of HIV infection amongst gay men is nowhere near 1 in 3.
Nationally (in the UK) it is estimated that approximately 1 in 20 gay men has HIV. In London, it may be as high as 1 in 10, reflecting the very different lives of gay men in the cities to those of gay men in rural areas.
One in three gay men with HIV is unaware of the fact, which is where you might have got your own figure from.
