Hardly surprising given that the assumption, certainly from early medieval times, is that men are sexual beings and women are not. So both social attitudes and the law reflected, and still reflect this. There was decades ago a form of feminism that challenged this passive notion of women. But in general the huge advantages of claiming to be helpless putty in men's hands (so never responsible for you bad behaviour and choices) outweighed the wish to be seen as capable of sexual desire and making good or bad choices.
