I'm talking about mainly in the US...well what I saw of it back then.

Ok, went looking online for info...
The reason anal as opposed to vaginal sex is so dangerous has to do with the difference in tissue construction between the male urethra and rectum and the female vagina. While the vagina is constructed of tough platelike cells that resist rupture and infections agents, and are designed to withstand the motions of intercourse and childbirth, the urethra and rectum are constructed primarily of columnar cells which tear or rupture easily. This allows semen to enter the more readily accessible blood vessels of the rectum or, conversely but much more rarely, allows blood from a ruptured rectum to seep into the urethra of the active partner. (The April 1987 AJPH study found that men who reported rectal bleeding were far more likely to become HIV positive than those who did not.)
There are other factors in the AIDS-anal sex connection. The vagina provides natural lubrication, whereas there is little in the anus. Anal douching, a practice many homosexuals engage in prior to intercourse, can remove what lubrication there is. The absence of lubrication not only increases the chance of rupture, but at the same time it reduces the efficiency of condoms by allowing them to tear.
