No, you wilful idiot. It's mostly about networks.

You wont' get HIV "networking" with Mrs A.

But the kids you teach will be exposed to infection when/if they "network" in the local nightclubs on a regular basis. That is how they contract so many other STI's

Gay men face greater risk because they are members of a far tighter sexual network.

Africans (in Africa) have had an epidemic in the general population because of the networking symbiosis of labour and political migration with prostitution, coupled with poor access to education, healthcare, diagnosis and ART treatment which - most critically - breaks the mother to child tranmission vector that has shot HIV through generations of Africans.

The reasons for different groups suffering HIV in different ways are NOT PRIMARILY differentiated by behaviours.

And thank you for confirming that I have only made the one comment that excites you so much, rather than the "rabid anti-straight gibes" that you incorrectly described.

You and I both know the context to that, so does everyone else.
