Women, does this picture make you feel effeminated?

The term “emasculate” is plum strange. It’s often used in the context of a woman outmanning the man in question. Like if Danielle pays for Daniel’s chipotle, Daniel may feel emasculated. If Betty Joe changes Billy Jim’s tires – emasculated. If Claire Bear benches more than T-Gainz – emasculated. But.. why? How? Shouldn’t masculinity be something within a man, that external forces cannot change?

This is especially confusing because there’s no equivalent term for women …
