I would like to say it could be true that being a husband of a beautiful lady is more challenging because men externally or internally care more about women's looking than anything else. On the other hand, being a beautiful lady is challenging as well, because it is hard to tell whether the man who says he loves you is only because of your looking or not. In another word, it's easier for a not-ugly woman to find a true love than a beautiful lady.
I guess it's partially because it's still a male-domenant sociaty, so all the women put on their best make-up in order to feel good. Imagine, when there's a time that all men put on their make-up and best suit to attract women......... that'll be so thrilling.
P.S. true love here means that nomatter how old, how poor, how ill you get, he is still by your side. --- I define.
