lots of married men have gay sex outside of marriage

Can you back that up?
That seems a sweeping statement that the numbers don't support.
Homosexuals are a very small portion of the population, despite how loud they are. If "lots" of married men were having gay sex and spreading HIV/AIDS, then you would have a much higher proportion of women with HIV/AIDS that were not drug users and/or promiscuous.

You're right. Just looked up the info. A book written by Michael Fumento called The Myth of Heterosexual AIDS. Written over 15 years ago. CDC predicted, motivated by PC influences, that by early 90's AIDS would become a heterosexual disease too. Of course, that never happened.

"Can you back that up? "

This is anectdotal, but I have lived across the street from a homo male, who was living with a female, with kids. My wife had a outed gay supervisor, who had once had a wife and child. Happens all the time. Oh, yeah, just remembered a female lesbian that I used to work with, and she had an ex hubby and chillun.
