Hands down, some of us are just deaf to flirting. Because it’s portrayed as so much more uncommon that a Girl flirts with a Guy. You are 100% right. But I’ve seen dudes getting hit on with a Baseball bat, and they were like “Whaaat? You sure?!” I tried to help a Girl Friend of mine out to set her up with another friend of mine. Bro was dumb as a Golden Retriever but twice as loyal. And now they are going steady for years.
