I don't like armored bikinis because they're stupid. Boobplate is fine though, we probably would have had that in the real world if we'd had a society with a large number of women in the fighting nobility.
That's not what people mean when they talk about sexualized armor. That armor at least has protective value. The actual sexualized male equivalent of that armor would consist ONLY of the codpiece and nothing else at all.
That's why I made the distinction between bikini armor and boob plate. The male equivalent to bikini armor is the fur loincloth / bare chest of the barbarian character. While I see boob plate as the female equivalent to dong armor. They're both fully protective suits of armor with exaggerated sexual characteristics molded into the outward appearance.
