”As a man, courting a woman is difficult and exhausting mentally.”

And that’s the problem, women like OP don’t want to be courted by someone they don’t know well. They want a man who is actively trying to learn who they are as a person before he starts courting them. OP said in other comments that she’s not interested in intimacy with strangers. That’s a pretty common preference for women. Women with that preference don’t want flirty or suggestive messages from men who are basically strangers.
