Homosexuality and HIV

I just read an article in the New York Times "Obama to Outline Plan to Cut H.I.V. Infections" that sparked my interest. Now, I would like HIV infections and the development of AIDS to decrease too, but I think sometimes the obvious is ignored.
Over 50% of those diagnosed with HIV are gay or bisexual men. I think it should be obvious, then, that decreasing sexual activity between men would cut HIV cases.

The Bible is very clear that those who engage in homosexuality with suffer physical effects.
Romans 1:26&27
For this cause God gave them up unto vile passions: for their women changed the natural use into that which is against nature: and likewise also the men, leaving the natural use of the woman, burned in their lust one toward another, men with men working unseemliness, and receiving in themselves that recompense of their error which was due.

Receiving IN themselves.

So, if the government is going to increase federal spending to help the men of the gay and bisexual lifestyles with their HIV problem, what is going to keep them from changing? Nothing. And if government aid is available to prevent HIV or lessen its effects, why wouldn't there be an increase in gay and bisexual lifestyles? It's a cycle.
