And while we are being candid, let's just clear up this whole 'gay plague' thing. As a percentage of the whole group, gay men suffer disproportionately with HIV infection.

The numbers show that this will soon be a historical irrelevance.

One of the reasons is the smaller pool of carriers. Infection can spiral very quickly. There is no moral dimension to this. It's plain old bad luck.

The other reason is that the primary vector is penetrative sex - where the options for gay men who wish to practice penetrative sex are limited. IS limited to anal sex.

Anal sex is a more efficient vector than vaginal sex because of the greater risk of tissue damage and bleeding. Again, no moral dimension. Just mechanics.

Vaginal sex can result in the same sort of tissue damage as anal and of course, as google will tell you and as the bible, torah and quran will confirm, straight couples have always enjoyed a bit of back door action.

In healthy, clean vaginal intercourse, the transmission rate where one partner is positive is A BIT less than in anal intercourse.

If the vagina, anus or penis is damaged or sore from, say, another STI, then the risk of transmission is multiplied across all vectors.

Keith, you have claimed to be a scientist, am I right or am I right in the sense of a general overview here?
