What about HIV incidence in gay women? Doesn't it deserve a mention?
TL;DR:
* 66% of recorded infections are in the gay/MSM population;
* 23% of recorded infections are in the straight population
The site doesn't provide the actual statistic for gay women/WSW, but those two numbers imply that it's around 11% (+/- 2% for the transgender population, which is also not clearly factored out.)
