This steady infection rate suggests that every year there are 40,000 new gay guys who get hit with it ~ odds are they are a substantial portion of all the new gay guys on the gay meat markets too.
So, let's say gay guys live 100 years. Then, over a century, there'd be 4,000,000 gay guys. At the same time there'd be 250,000,000 or so non-gay guys born (if non-gay guys only lived 76 years or so). That'd mean (4/250 = .016) or a maximum of 1.6% of the male population who ended up gay.
Of course, there are many fewer gay guys than I project, so they've gotta' be down less than 1%.
(I know somebody is going to argue that 100% of gay guys don't get aids ~ but how do you know unless you use a projection method that assumes the percentage of gay guys in the population is far greater than 1%.)
This number of gay guys also pretty well conforms to the best estimates of how many pedophiles there are who prey on young boys.
No doubt that's merely coincidental.
40,000 new cases aren't necessarily "new meat". There could be some who've dodged a bullet with their risky behavior several times and it finally caught up with them.
