I am male. Ergo anything I think, say, or do is inherently masculine. When I’d let my wife paint my nails, they were manly painted nails because they were attached to a man. If I drink a fruity mixed beverage, it is a manly beverage because a man ordered, paid for, and is drinking it. If I drive a Miata it… actually that is kinda girly, but I’ll do it anyway.
