No, it is not. Lack of medical care, lack of education, lack of choices in careers - in simple terms poverty - are the main causes of AIDS worldwide.
Gay men didn't even originate AIDS. Take a look at this report from the
BBC
No matter how hard the facts are manipulated the main cause of AIDS is still poverty. AIDS and homosexuality are not linked, worldwide, in a way that somehow shows any special condemnation of homosexuals.
I know that "AIDS=Homosexual Americans" theories presented by many fall apart when worldwide statistics are examined, which is exactly why I am posting them.
Another cause is the marginalization of a sub-group within a wider population. An example right in the USA is African American women.

So my point, you see, is that the idea in the OP is easily disprovable. Even the wrongly-title "gay bowel syndrome" can occur to women giving birth! And it does happen often in some place. Some facts on fistula (the proper term) from the
Fistula Foundation and also to women who participate in sodomy, often with their husbands.
