A lot of this is grossly exaggerated and anecdotal, and actually rooted in homophobic tropes from the Reagan era so as to dismiss HIV as a “human disease” and instead condemn it as a “gay disease” that the LGBTQ+ had coming its way. The average US gay man has had no significant number of sexual partners more than the US straight man, and this has been backed up by study after study. Do you have actual sources?
Anyways, in absolute numbers now there’s more heterosexual people who are testing positive for HIV than gay people in the West (and it’s been the case globally for a while, too)
