Joe, the ONLY way to reduce the incidence of STD amongst male homosexuals, is to cut transmission rates drastically.

The MSM demographic should be targeted with more frequent testing and contact tracing. As Keith has mentioned, the agencies are looking at an "opt out" system, where MSM will be routinely tested, unless they specifically refused to allow it.
Their hands are of course tied by human rights and anti discrimination legislation, which in this case is working against the interests of male homosexuals.

Personally, I think that more should be done by homosexuals themselves to defeat this epidemic and have suggested a voluntary register, which could be run by Ian's friends in Stonewall.
All active male homosexual would volunteer to be tested perhaps four times a year or whenever starting a new sexual relationship.
My main point being, that before long, for MSM NOT to be tested would become socially unacceptable within their own circle, just as smoking in public and drunk driving has become socially unacceptable in mainstream society.

I think that male homosexuals need to be seen to be willing to help themselves, before this dreadful health problem can be properly addressed.
