Physiological gender and practical gender are different things.
Jim, when I hear you saying "usually male", what I really hear is that, generally speaking, the formula of interaction between the aspirant and the HGA has the Angel as positive and the aspirant as negative.
More likely than not we are "receiving" something in any case, and I don't know about any of you, but in the low, sexual parallel of what we call "knowledge and conversation", I have definitely been on the receptive end of the interaction with both men and women...so do whatever you want with that.
