You might personally be irritating to her, but that really doesn't have anything to do with OP's comment.I was curious so I just now posed this question to a South Indian woman and she said "because you're really irritating" and I guess that's fair
You could do that with white women, too. Perhaps most women, regardless of race.There isn't much sexual dimorphism in black people. Other than tits, if you shave a black woman's head she will look no different than a black man of similar build.
On the other hand, lack of feminine behavior from black women is a complaint I've heard repeatedly from black men.Reflexively, many black men look to other races that show more femininity.
