Why women rarely invite men?

Although difficult to generalize, the international norm is men usually inviting women for food and drinks. Especially in Africa and most probably in Asia, it is men inviting women. Even if the women are richer than men, the culture is men who invite women.  Why is it so?

The reason, in my opinion, is that if the woman invites the man, the man automatically interprets it as the woman is seeking for sexually intercourse which actually is not in the mind of the woman. Should not this culture be reversed with gender equality?

It is true that this is not a worldwide culture. My friend who stayed in Norway told me that it is women who drinks in bars while men at home cooking. By implication, it should be women inviting men in Scandinavian countries. If my friend told me the truth, this again is a culture of feminism which is not acceptable. But the culture of most countries is masculinism and that is why men are the inviter than women. Is it not?
