Dave, I said that "ALL male homosexuals are not promiscuous", the figures suggest that a large majority ARE. Male homosexuals are a recognised demographic by health agencies in the UK and the US, known as MSM. This demographic accounts for over 70% of all new cases of HIV and Syphilis...... as well as higher rates of STD infections in every country in the the world. This demographic accounts for under 2% of the population (lesbians are not affected)

Why are these transmission rates so much higher than those for heteros?......I would think it obvious that promiscuity, risk taking, and addiction to anonymous relationships may play a part....wouldn't you.

Of course, there may be another reason associated with the physical practice of male to male sex......is that what you had in mind?
