But as we know, older men with young women who marry them because money are the ones who should be more worried about loyalty. I mean, Arthur married Ginebra only for her to cheat with younger and handsome Lancelot. It is al recurring story. So looking for much younger, inexperienced women won't get you loyalty. After all, she might think about all the things that she hasn't experienced and start looking elsewhere... So I don't think it is evolution, just your preferences. XD
