i must say that i am shocked that there is nothing about demographics in this article because i think a lot of people are going to be coming to this article for that kind of information.  they want to know about the percentages of men compared to women, ethnicities, social practicies and stuff.  i tink it would be fair to add that even though it is not a gay disease or anything like that there is science explaining why homosexuals get more HIV. for example, some (not all) do it in the bootyhole with other men unprotected, and it doesn't stretch the way the vag does, which means it's more likely to cause tearing and bleeding, and that means gay sex will cause more HIV when unprotected by the condom.  the connection betweeen HIV and sex education, affluence, geography, and attitudes might be what people come here to know also.
