He had the balls to ask me out

[Abstract Idea]

Maybe you meant "used to describe men"? Well, I think that's not entirely true either (see this for example).

That is what I meant. I thought it was implicit. But your remark is completely pertinent. I said that in normal conditions a lady should not state that she 'has the balls'.
Of course I am talking about someone learning English. If she knows exactly what that means and in a certain situation she wants to use it, just go for it. What is more important is to express herself, no doubt about it.

Sorry fivejedjon. I don't know if I used the wrong word or if you are just joking and being sarcastic.

You used the right word. My post was a (not very) humorous attempt to suggest that the idea that men are more courageous and strong (in several senses) than women is not prejudice. The implication was that it was fact.

Did you think this question wasn't adequately answered already?
