There may be those who have first felt mere sexual appetite for a woman and then gone on at a later stage to “fall in love with her”. But I doubt if this is at all common. Very often what comes first (with true love) is simply a delighted pre-occupation with her in totality. A man in this state really hasn’t leisure to think of sex. He is too busy thinking of a person. The fact that she is a woman is far less important than the fact that she is herself.
