Yellow fever exists because most Asian women are thin.  The size of their breasts has little to do with it. (~25 BMI might be attractive but it requires that the weight all goes to the right places.  That's not the case with all people.) Also, tall women shouldn't fell any less womanly.  As long as they aren't overweight, men still want to fuck them.  (Despite the wailing and chattering of some Pick-Up Artists.)
