"When harems become the norm, homosexuals multiply, huh."

I sometimes see novels on "Naro" about reincarnating into a world where harems are the norm, but I had this simple question: wouldn't that actually result in a surplus of men and inevitably become full of gay people~~? Even if you dream of indulgent harems, an ordinary herbivorous guy like me would just get eaten up by carnivorous gays (゜∀゜). I've attached a Boys Love tag just in case, but this is more just gay jokes than actual BL ┌（┌＾o＾）┐
