Whether this is generally true or not, I couldn't say. Nor do I know how such a generalization could be substantiated.
But it is not true in every instance. I know a couple of homosexual women in a "relationship" who have been together for years without having sex; one of them, in her mid-60's, remains the devoted caregiver of the other, a disabled Alzheimers sufferer in her late 70's.
First of all, MOST people, normal or queer, are propablely not having sex at that age. By then, most are sexually retired.
Secondly, how do you know they're not having sex? Just because one is unaware of it doesn't mean the other isn't being hands on.
BTW: The female homosexuals aren't as aggressive and threatening to the human race as the males. Other than shouting their mouths off, they're at least, or mostly, disease free, and they're not as physically as aggressive or dangerous as the male homosexuals. Maybe because they're not overdosing, and their brains are left undamaged?
Is this from the article? I don’t remember reading that.
